Prefilled syringes require careful evaluation of their sealing components and interfaces. Container Closure Integrity Testing helps manufacturers identify potential leak pathways and verify that the package can maintain its integrity throughout its intended shelf life.

Why Is Container Closure Integrity Important for Prefilled Syringes?

Prefilled syringes contain medicines that must remain protected from contamination and environmental exposure throughout their intended shelf life. Unlike simple containers, a prefilled syringe contains several components and interfaces that can affect package integrity.

Small defects or gaps at these interfaces may create potential leak pathways. Therefore, manufacturers need to evaluate the complete system and individual sealing areas when developing a CCIT strategy.

What Should Manufacturers Consider When Developing a CCIT Strategy?

The first step is to understand the complete prefilled syringe configuration. Manufacturers should identify components and interfaces that could contribute to a leak and determine which areas require testing.

Manufacturing conditions should also be considered because dimensional variation, assembly conditions, component fit, and handling can affect container closure integrity. The CCIT strategy should also consider stresses that may occur during storage and transportation.

How Should the CCIT Method Be Selected?

The test method should be selected according to the syringe design, testing objective, required sensitivity, and stage of the product lifecycle. USP <1207> provides a framework for package integrity evaluation and the selection and validation of leak test methods.

For prefilled syringes, deterministic methods can be useful when manufacturers need objective and measurable information about package integrity. The selected method should be validated using the actual package configuration and appropriate known defects or reference standards where applicable.

How Does Helium Leak Testing Support Prefilled Syringe CCIT?

Helium leak testing uses helium as a tracer gas to identify potential leak pathways. A mass spectrometer detects helium that passes through a leak and provides quantitative leak-rate information.

For prefilled syringes, testing can focus on the complete syringe or specific areas such as the plunger, barrel, tip, needle interface, or rigid needle shield. Custom fixtures can help position the syringe correctly and provide access to the area being evaluated.

How Does SIMS 1915+ Technology Support Testing?

SIMS 1915+ Technology can be used with suitable fixtures to support helium leak testing of pharmaceutical packages, including prefilled syringes. The system detects helium through potential leak pathways and provides quantitative leak-rate measurements.

Testing may be performed on the complete prefilled syringe or on selected components and interfaces, depending on the test objective. This approach can help manufacturers investigate critical sealing areas during package development, validation, and failure analysis.

Conclusion

A well-planned CCIT strategy for prefilled syringes requires more than testing the final assembled package. Manufacturers should understand the syringe design, evaluate critical sealing interfaces, consider manufacturing and transportation stresses, select an appropriate test method, and establish suitable acceptance criteria. Following the principles described in USP <1207> can help provide a structured approach to container closure integrity evaluation.

By applying these practices throughout the product lifecycle, pharmaceutical manufacturers can obtain quantitative evidence of vial integrity and better understand the performance of their container closure systems.

Product stability studies help pharmaceutical manufacturers determine whether a drug remains safe, effective, and of high quality throughout its shelf life. During these studies, products are stored under different conditions, such as changes in temperature and humidity, to see how they perform over time.

For stability studies to provide accurate results, the packaging must remain completely sealed. If the container develops even a tiny leak, moisture, oxygen, or microorganisms can enter the package and affect the product. This may lead to incorrect stability results. Container Closure Integrity (CCI) testing helps confirm that the package continues to protect the product during storage.

Why is Container Closure Integrity Important?

The main purpose of a container closure system is to keep the pharmaceutical product safe from outside contamination. Packaging such as vials, syringes, cartridges, blister packs, and pouches must remain sealed throughout the product's shelf life.

If the package loses its integrity, the product may be exposed to environmental conditions that reduce its quality or sterility. By performing Container Closure Integrity Testing (CCIT), manufacturers can verify that the package remains properly sealed during stability studies.

How can Package Integrity Affect Product Stability?

Package integrity plays a direct role in maintaining product stability. A damaged or leaking package may no longer provide the protection needed to preserve the product.

Some common problems caused by package leaks include:

• Moisture entering the package
• Oxygen causing product degradation
• Microbial contamination affecting sterility
• Reduced product quality during storage
• Shortened product shelf life

A properly sealed package helps ensure that stability study results reflect the performance of the product rather than the condition of the packaging.

How does CCIT Support Stability Studies?

Container Closure Integrity Testing is used to check whether a package remains sealed before, during, and after stability studies. It helps manufacturers identify package defects that cannot be seen during visual inspection.

CCIT offers several benefits:

• Detects very small leaks
• Provides reliable and repeatable test results
• Confirms package performance during storage
• Helps identify sealing problems early
• Supports better quality control

Using CCIT gives manufacturers greater confidence that the packaging is protecting the product throughout the stability study.

How does Helium Leak Testing Help?

Conclusion

Even the smallest leak can compromise package integrity and affect stability results. Container Closure Integrity Testing helps confirm that packages remain properly sealed during storage. Using sensitive methods such as helium leak testing, manufacturers identify leaks at an early stage to improve package performance while ensuring the quality, safety and reliability of their pharmaceutical products.

Container closure integrity (CCI) is one of the most important requirements for sterile pharmaceutical packaging. Injectable drugs must remain protected from contamination and environmental exposure from the time they are filled until they are administered to patients. While the vial itself is designed to provide protection, the stopper and crimp seal are the components that complete the closure system. Their quality has a direct impact on the ability of the package to maintain a reliable seal.

What Is Container Closure Integrity?

Container closure integrity (CCI) is the ability of a sealed pharmaceutical package to keep the product protected throughout its shelf life. It prevents contaminants such as microorganisms, moisture, and gases from entering the container while also preventing the drug product from leaking out.

For sterile injectable drugs, maintaining a reliable seal is critical for preserving product quality, stability, and patient safety. Even a microscopic leak may not be visible, but it can allow contaminants to enter the vial over time, potentially affecting the product before it reaches the patient.

The Role of Stoppers in Vial Sealing

The elastomeric stopper forms the primary seal between the vial and the external environment. When properly compressed, it creates a tight barrier that prevents contaminants from entering the package while keeping the drug product securely contained.

The aluminum crimp seal holds the stopper in place and maintains the compression required for an effective seal. Both components must work together to achieve reliable container closure integrity. If the stopper is damaged, improperly positioned, or incompatible with the vial, or if the crimp seal is applied incorrectly, the sealing performance may be compromised.

How Crimp Seal Quality Affects Container Closure Integrity?

Crimp seal quality directly influences the effectiveness of the closure system. Too little crimping force may leave the stopper insufficiently compressed, while excessive force can damage the stopper or deform the seal. Inconsistent sealing can create microscopic leak paths that are not visible during routine visual inspection.

Other factors that may affect closure quality include damaged stoppers, vial finish defects, dimensional variations between components, and improper stopper placement. Although these issues may appear minor, they can significantly reduce the package's ability to maintain sterility throughout storage and distribution.

Why Microscopic Leaks Are Difficult to Detect?

Many closure defects are too small to be identified through visual inspection alone. Traditional inspection methods may not detect microscopic leaks that can allow gases, moisture, or microorganisms to enter the vial over time. As pharmaceutical products such as biologics, vaccines, and other sterile injectables become increasingly sensitive, identifying these extremely small leaks has become more important than ever.

Reliable container closure integrity testing provides manufacturers with greater confidence that packaging systems will perform as intended throughout the product lifecycle.

How SIMS 1915+ Uses Helium Leak Testing for Vial Inspection?

Conclusion

Stopper and crimp seal quality are critical factors in maintaining vial container closure integrity. Even small variations in sealing components or sealing processes can create microscopic leaks that affect product quality and sterility. By combining high-quality packaging components with advanced deterministic technologies such as SIMS 1915+, manufacturers can accurately verify package integrity, identify defects early, and ensure sterile pharmaceutical products remain protected from manufacturing through patient use.

Plastic packaging is widely used in the pharmaceutical and biotechnology industries because it is lightweight, durable, and versatile. Maintaining package integrity is essential to protect products from contamination and preserve their quality throughout their shelf life. Helium leak testing is a highly sensitive method used to detect and measure package leaks, but its use with plastic packaging is often questioned due to the material's natural permeability to helium. Despite this challenge, advances in helium leak detection technology have made it possible to accurately evaluate plastic packaging and identify true package defects. This article explores how helium leak testing can be applied to plastic packaging and the factors that enable reliable package integrity testing.

What Is Helium Leak Testing?

Helium leak testing is a deterministic container closure integrity testing (CCIT) method that uses helium as a tracer gas to detect and measure leaks in sealed packaging systems. A package is typically filled with helium and exposed to a vacuum environment. Any helium escaping through defects is measured using a highly sensitive mass spectrometer, providing a quantitative leak rate. This makes helium leak testing one of the most sensitive methods available for package integrity evaluation.

Why is Plastic Packaging Considered Challenging for Helium Leak Testing?

Unlike glass or metal containers, plastic materials are naturally permeable to gases. Helium molecules are extremely small and can diffuse through many polymer structures over time. As a result, helium detected during testing may originate from normal material permeation rather than an actual package defect. This characteristic has led some manufacturers to assume that helium leak testing is unsuitable for plastic packaging. However, with the right testing approach, helium leak detection can be effectively applied to plastic packaging systems.

How can Helium Permeation Be Managed?

Understanding the difference between helium permeation and a true leak is essential when testing plastic packaging. Modern helium leak testing systems can be configured to account for the natural permeation characteristics of plastic materials. By optimizing test parameters and using appropriate methodologies, manufacturers can distinguish background permeation from actual package defects. This enables reliable package integrity assessments even for helium-permeable packaging systems.

What role do Fixtures and Tooling Play?

Proper fixture design is important when testing plastic packaging. Customized tooling helps securely hold the package and control helium flow during testing. Specialized fixtures can reduce testing variability and improve the ability to identify true leak paths. These engineered solutions let manufacturers to evaluate plastic packaging with a high degree of accuracy and confidence.

What Types of Plastic Packaging Can Be Tested?

Helium leak testing can be applied to a wide range of plastic packaging formats, including:

• Polymeric vials

The SIMS 1915+ adds to the testing capabilities with very sensitive and quantitative leak rate measurement.

Container Closure Integrity Testing (CCIT) is essential for ensuring the sterility, safety, and quality of pharmaceutical and medical device packaging systems. As the industry continues to move toward deterministic testing technologies, helium leak detection has become one of the most reliable methods for detecting and measuring package leaks.

Helium leak detection uses helium as a tracer gas combined with mass spectrometry technology to identify extremely small leaks in packaging systems such as vials, syringes, cartridges, blister packs, and flexible pouches. Due to its high sensitivity and quantitative capabilities, helium leak testing is widely used in pharmaceutical and biotechnology applications.

Why Validation is Important in CCIT ?

Validation is a critical part of helium leak detection because it confirms that the test method consistently produces accurate and repeatable results. In sterile pharmaceutical packaging, even very small leaks can impact product quality, sterility, and shelf life.

USP <1207> recognizes helium leak detection as a deterministic method because it provides measurable and objective leak rate data rather than subjective visual interpretation. Proper validation helps manufacturers establish reliable leak detection limits and maintain confidence in package integrity testing.

Validated helium leak testing methods are commonly used for:

• Vials and ampoules
• Prefilled syringes
• Cartridge systems
• Blister packaging
• Flexible packaging systems

Using Calibrated Leak Standards

One of the most important best practices in validation is the use of calibrated helium leak standards. These standards help ensure the accuracy and consistency of the testing system.

Calibrated standards are used for:

• Daily system verification
• Instrument qualification
• Method validation
• Performance checks
• Ongoing quality monitoring

PTI’s SIMS 1915+ helium leak detection systems include internal and external calibrated leak standards that support reliable and repeatable testing performance.

Using calibrated standards also helps maintain long-term consistency in leak rate measurements.

Establishing Leak Rate Acceptance Criteria

Helium leak detection provides quantitative leak rate measurements, allowing manufacturers to establish scientifically defined acceptance criteria for package integrity.

Leak rate limits are typically based on:

• Package design
• Product sensitivity
• Stability requirements
• Storage conditions
• Risk of microbial ingress

Helium leak detection can detect leaks as small as one micron, making the test highly sensitive, which cannot be achieved using conventional testing methods.

Ensuring Accurate and Repeatable Results

Accuracy and repeatability are essential for successful validation. Validation studies should confirm that the helium leak detection system consistently produces reliable results across multiple tests and sample sets.

Best practices for improving repeatability include:

• Performing routine calibration checks.
• Using certified leak standards.
• Maintaining controlled testing conditions.
• Conducting regular instrument verification.
• Monitoring system performance over time.

Automated helium leak testing systems also help reduce operator variability and improve testing consistency.

Evaluating Temperature and Environmental Conditions

PTI offers helium leak testing systems designed for low-temperature applications, including testing environments down to -140°C. These systems help manufacturers identify leaks that may develop due to material contraction or elastomer changes during cold storage.

Testing only at room temperature may not accurately represent real-world package performance.

Conclusion

Validating helium leak detection methods in CCIT is essential for ensuring accurate, repeatable, and reliable package integrity testing. By using calibrated leak standards, establishing quantitative leak rate criteria, evaluating environmental conditions, and maintaining regulatory compliance, manufacturers can strengthen product quality and sterility assurance.

As pharmaceutical packaging systems continue to evolve, helium leak detection remains one of the most sensitive and effective technologies available for modern CCIT validation applications.

Vials are widely used in pharmaceutical packaging to store injectable drugs, biologics, and vaccines. They must maintain a strong sterile barrier to protect the product from contamination and environmental exposure. However, even extremely small leaks in the vial closure system can compromise product quality. To ensure packaging integrity, advanced methods like helium leak detection are used to identify sub-micron defects with high sensitivity and accuracy. As regulatory expectations around container closure integrity (CCI) continue to evolve, the need for precise and reliable leak detection technologies has become increasingly important.

Why Sub-Micron Leaks Are Important to Drug Safety and Stability ?

Sub-micron leaks represent a significant risk to pharmaceutical products, particularly those requiring strict sterility. These microscopic defects can allow the ingress of oxygen, moisture, and microorganisms, which may gradually degrade the product or alter its chemical composition. For biologics and other sensitive formulations, even minimal exposure can impact efficacy and patient safety.

Even the smallest leaks can disrupt the vacuum or protective gas environment inside a vial, exposing the product to oxygen and moisture. This exposure can speed up degradation processes, ultimately affecting stability and reducing shelf life. Since these leaks rarely produce immediate or visible signs of failure, they can remain undetected without highly sensitive testing methods. Therefore, precise leak detection is essential to ensure product integrity over time.

How Helium Leak Detection Identifies Extremely Small Leaks ?

Helium leak detection is a highly accurate method used to evaluate vial integrity. Unlike traditional techniques that estimate leakage indirectly, HLD directly measures the actual leak rate by detecting the amount of helium escaping from the container. This provides precise and real-time results, typically expressed in units like atm·cc/sec.

Helium is ideal for this process because it is a very small and inert gas, allowing it to pass through extremely tiny leak paths. With advanced mass spectrometry systems, Helium leak detection can detect leaks smaller than 1 micron. This makes it possible to clearly identify even very small differences in leak rates that other methods may miss.

Benefits of Early Leak Detection in Product Development

Integrating helium leak detection early in the development process provides significant advantages. During package design and validation, the ability to measure true leak rates allows manufacturers to optimize vial closure systems and materials with greater confidence.

Early detection of sub-micron defects helps reduce the risk of failures later in the product lifecycle, minimizing costly recalls and regulatory challenges. It also enables the establishment of clear, quantitative acceptance criteria aligned with regulatory expectations.

For example, in the development of sterile injectable drugs or lyophilized products, helium leak detection can reveal micro-defects that might otherwise go unnoticed. Addressing these issues early improves overall product robustness, enhances shelf life, and ensures consistent performance from development through commercialization.

Conclusion

As pharmaceutical packaging becomes more advanced, ensuring vial integrity at the smallest level is critical. Sub-micron leaks, though invisible, can significantly impact product safety, stability, and compliance. Traditional methods often fall short in detecting these defects with the required precision.

Helium leak detection provides a highly sensitive and scientifically robust solution by directly measuring active leak rates in real time. Its ability to deliver accurate, quantitative, and temperature-relevant data makes it the benchmark technology for modern container closure integrity testing. By adopting helium leak detection, manufacturers can strengthen quality assurance, support regulatory compliance, and ensure the delivery of safe and effective pharmaceutical products.

Pharmaceutical cartridges are small, sealed containers designed to hold specific dosages of liquid or solid medications. They are often made of glass or plastic and are designed to be used with specific equipment, such as pre-filled syringes and autoinjectors. Traditional sterility testing has been replaced by advanced technologies such as Container Closure Integrity (CCI) that provide more efficient test procedures. The main objective is to make sure that impurities, including gases (particularly reactive ones), microbes, and other external materials, are unable to break down a closed system's barrier of defense. Otherwise, these impurities may damage the system's sterility or the enclosed drug product.

Pharmaceutical manufacturers place a high premium on the integrity of packaging components in a field where the risks are extremely high. Serious consequences, such as contamination and decreased efficacy of life-saving medications, might result from a defect in a vial, syringe, or ampoule. Helium leak testing has become a commonly used technique for evaluating the integrity of different pharmaceutical components in order to guarantee that packaging stays airtight and secure. Helium leak testing is a critical quality control method used in the pharmaceutical industry to ensure the integrity of drug containers, including cartridges.

Helium Leak Testing vs. Traditional Methods

Helium leak testing offers significant advantages over traditional methods for detecting leaks in pharmaceutical cartridges. Unlike pressure decay tests, which measure pressure loss over time and are less sensitive to small leaks, helium leak testing utilizes the unique properties of helium gas to detect even the micro leaks and defects. This technique surpasses the limitations of dye ingress test, which relies on visual inspection and is less sensitive to micro-leaks. By providing quantitative results, helium leak testing enables precise measurement of leak rates, allowing for data-driven quality control. Its versatility further enhance its efficiency and reliability, making it a preferred choice for ensuring product integrity and patient safety.

Testing Integrity of Pharmaceutical Cartridges Using Helium Leak Detection

Helium leak testing is a quality assurance process for pharmaceutical cartridges. This technique utilizes helium gas, an inert and atomically small tracer gas, to detect minute leaks in sealed cartridges. By pressurizing cartridges with helium and subjecting them to a vacuum environment, any defects will allow helium to escape, triggering sensitive detectors.

Helium leak testing is highly sensitive, capable of detecting leaks as small as 10^-10 mbar L/s. It is also fast and efficient, allowing for high throughput testing without compromising accuracy. Moreover, it is versatile, applicable to various cartridge designs and materials. By using helium leak detection, pharmaceutical manufacturers can adhere to strict regulatory standards and deliver reliable, safe products to patients.

Beyond standard testing conditions, helium leak testing proves invaluable for products stored at ultra-low temperatures. As the pharmaceutical industry increasingly relies on deep cold storage for complex formulations, helium's ability to maintain reliability in extreme conditions ensures the integrity of cartridges and their contents.

Helium leak testing is essential in the pharmaceutical sector to guarantee secure and efficient drug delivery, particularly in cartridges. This protects patient safety and product quality by using the special qualities of helium to find minute leaks. Helium leak testing is still a crucial instrument as laws and patient expectations rise. It enables producers to provide dependable pharmaceuticals, reaffirming their dedication to patient care and industry development.

The integrity of the seal between the container and the closure is a major concern when choosing packaging components for a parenteral drug product. The packaging must protect the pharmaceutical product from a number of possible sources of contamination, such as microbial ingress. Container closure integrity (CCI) is defined as the capacity of a container closure system to preserve a drug product and hence retain its efficiency and sterility throughout its shelf life. The purpose of container closure integrity testing is to determine the effectiveness of packaging closure.

To ensure CCI of pharmaceutical drugs, a number of methods are used. Helium Leak Detection is one of them. In this method, helium is used as a tracer gas, to detect leaks. This testing produces quantitative data that are more repeatable and reliable than qualitative pass/fail results. Despite the fact that it is a destructive test, helium leak testing is widely used because of its sensitivity and ability to run samples at temperatures below ambient. After the sample is prepared, it may be kept and analyzed at the proper temperature.

CCI Testing of Pharmaceuticals at Low Temperature

The CCI of pharmaceuticals may be determined using a variety of approaches. Under sub-ambient temperature circumstances, several methods of container closure integrity testing, such as blue dye ingress, microbial ingress, and vacuum decay, are insufficiently sensitive or simply unsuitable. Helium leak testing is a reliable method for testing closures and ensuring product effectiveness and sterility. This method is more sensitive than other CCI testing methods.

PTI has created the LT80, Low Temperature -80°C, Add-On test system for use with the PTI SIMS helium leak detectors to meet the market demand for analyzing leaks at cold temperatures. Concurrent temperature conditioning, temperature monitoring, and helium leak testing of packages approaching -80°C are all possible with the LT80 system. Even at temperatures as low as –80°C, helium leak detection is an effective method to ensure container closure integrity. While there are alternative methods for measuring CCI, many of them are ineffective at temperatures below –80°C. The LT150 low-temperature add-on unit allows for sample testing at temperatures as low as -150° C. The highly sensitive nature of the instrument allows for leaks as low as a 2µm hole can be recognized as a failure. The quantitative results provide the analyst with a numerical value, which allows for better data trends and greater confidence in the packaging system's performance than qualitative techniques can provide.

Container closure integrity or CCI, on packaging for parenteral drug products, is crucial for drug product preservation. The packaging closing components must be carefully chosen in order to eliminate sources of contamination that could harm the pharmaceutical product. The need to extend container closure integrity testing into the cryogenic temperature range is already becoming apparent. Container closure integrity must be achieved at cryogenic temperatures if pharmaceuticals are to be kept at cryogenic temperatures. For these types of drug items, newer packaging solutions like prefilled syringes and complex self-dosing devices are increasingly being used, and CCI will need to be proved for them as well.

What is helium leak detection?

The pharmaceutical industry has seen a significant rise in the use of pre-filled syringes in recent years. This demand is expected to accelerate over the coming decades. Pre-filled syringes offer benefits to the pharmaceutical industry in the form of reduced drug waste and increased product life span. Health care workers consider pre-filled syringes as an efficient, convenient and reliable drug administration method. However, they pose several challenges in manufacturing and require extensive testing.

Just like any other drug product, pre-filled syringes should be free from pyrogens and should be sterile. Not just that, they are expected to be biologically, chemically and physically stable throughout its shelf life. Considering the complex nature of these products, it isn’t surprising that there are many opportunities for it to fail to meet quality requirements. Defects in pre-filled syringes mainly depend on drug product design and syringe process design. Additionally, patient related issues are also an area of concern. Therefore, it is important for manufacturers to have knowledge and understanding of various tests involved to ensure patient safety.

Container Closure Integrity testing of pre-filled syringes

Sterility is the most important quality attribute associated with any pharmaceutical/ parenteral drug product. Container Closure Integrity (CCI) testing is one of the key tests performed by manufacturers so that the product is guaranteeing sterility and microbiological quality until point of use. Container closure integrity testing evaluates the ability of container closure systems to maintain a sterile barrier against possible contaminants that can deteriorate the quality of final pharmaceutical and biological products. There are multiple methods to conduct container closure integrity tests, each with its own set of benefits and limitations. For instance, techniques like dye ingress and microbiological ingress are destructive to the samples being tested. Such tests rely on statistically representative number of samples from the batch and assume that defects are uniformly present throughout the batch. On the other hand, deterministic methods are non-destructive in nature and can be used to test every unit from the batch.

Helium Leak Testing for Pre-Filled Syringes

Helium leak testing refers to the act of finding leaks in some type of enclosed or sealed system using helium as a “tracer” gas and measuring its concentration as it escapes due to leakage. Under this technique, the package is helium filled and subjected to vacuum. The amount of helium escaping the package is quantitatively measured with the help of a helium leak detector. The result is stated as a leak rate. Apart from being an effective container closure integrity test method, helium leak testing is also applicable in product design, product quality analyses, failure analyses and validation.

Why use helium as a tracer gas?

Helium is considered as an ideal choice of tracer gas because of the following reasons:

• Helium is non-toxic, non-condensable, non-flammable.
• It is inert, making it safe for use as it will not interact with the components being tested.
• The atom size of helium is really small, allowing it to breach pathways reliably and easily.
• Compared to other tracer gases, helium is less expensive and readily available.

The adoption of deterministic, quantitative test methods for comprehensive container closure integrity testing (CCIT) has become the norm over the past decade. Recent and future regulatory guidance directives have continued this trend. However, this trend of increasing scrutiny, and thus, increasing complexity for regulated companies, is not in vain. The benefits of such a method are plentiful, and their usage can span the entire lifecycle of a product-package system, right from development of the package, to stability, to analysis of package integrity after distribution cycles. In fact, the need for CCIT at multiple product lifecycle stages is explicitly discussed in USP <1207>.

In the current version of USP <1207>, there are a total of four subsections. USP <1207.1> discusses critical background information and rationale for the selection of an appropriate test method. Included in this subchapter is a detailed discussion of CCI evaluation during a product life cycle, which states: “Package integrity verification occurs during [at least] three product life cycle phases: 1) the development and validation of the product– package system, 2) product manufacturing, and 3) commercial product shelf-life stability assessments”. The idea behind such a statement is that CCI should be built into the design of the product-package system and the processes that yield it.

This is a notable shift from the somewhat pervasive tendency to consider CCI as a checkbox, something verified as a company is assembling documentation for a filing, perhaps after the final configuration and manufacturing has been finalized. This latter approach has inherently more risk. What if the vial-stopper configuration chosen does not have an ideal fit? What if the assembly parameters used for capping that vial do not yield consistently integral final packaging? Situations like this are not uncommon, and can lead to expensive changes, product recall, or risk to patient safety. Fortunately, modern, deterministic methods, such as helium leak detection, can help characterize and mitigate these risks.

Early on in the development process, the inherent integrity of the chosen product-package system should be evaluated, essentially answering the question: “Are these components, when mated optimally, capable of creating an integral seal?”. This concept is called inherent integrity, or whether the package components, as an inherent function of themselves, can create and maintain an integral seal. For a manufacturer considering the implementation of a stopper from a potential catalog or stock of many varieties, for example, a helium leak test study can be developed in order to assess the relative performance of each component. In the experience of LDA and its partners, there can be a significant difference between stoppers with the respect to their ability to create adequate seals, regardless of capping conditions. Future blogs in the LDA resource center will highlight these applications.

A specific, upstream and preventive CCI program that is gaining in popularity is that of a “Capping Study”; a program in which optimal sealing parameters are determined through correlation with low leakage rates. In such programs, there are typically a range of sample sets assembled at capping parameters from very low (aluminum crimp seal barely applied) to very high (possibly yielding stress cracks in the vial neck area). These samples are subsequently assessed for % compression of the stopper and residual seal force (RSF), an indirect measure of the amount of force the stopper is applying to the land-seal of the vial. The third, and most critical part of the triad, is helium leak testing. As each set of samples undergo helium leak testing, differences in leak performance between the sets can be identified. An ideal set of capping parameters that correlates to consistently low leak rates can be determined. Additionally, an ideal residual seal force range can be identified.

The correlations between capping parameters, RSF, and helium leak rate can be immensely valuable. For example, this work can be performed at lab-scale for development purposes, helping to inform final settings for a manufacturing setting. Manufacturing capping settings can be tailored to yield package RSF data in line with laboratory results. Package systems produced on that full-scale line can be further tested by helium leak detection as final confirmation and as part of a complete assembly validation for the product-package system and its assembly processes.

To further provide insight into the value of this approach, if product is being manufactured at 3 sites, the identified capping settings can be employed at each site, aiding in the transfer and validation process. More importantly, samples can be pulled from the line at each site and routinely checked by RSF. If the samples pulled off the line exhibit RSF values within a range that correlates to reduced risk of leakage and consistent with historical data, capping processes are likely under control. Although this does not guarantee package integrity, it provides an added layer of control, and can be referred to as an ongoing seal quality test. Similarly, helum leak detection can be employed on a routine basis for additional confidence, as helium would be considered a true seal integrity test.

Numerous capping optimization and assembly validation studies like these have been performed using LDA SIMS 1284+ helium leak detector and LDA’s unique range of accessories for the pharmaceutical and medical device industries. As the concept of CCI, and inherent CCI specifically, continues to be a topic regulatory agencies are more interested in, it is likely this trend of evaluating CCI in package development and validation will become an expectation. However, this change is one that should be welcomed by industry. Evaluating components prior to their use potentially prevents costly component changes down the road, and can lead to safer, less recall-prone packaging.

Presentation Summary

At the 2019 PDA Container Closure Integrity Testing Workshop in Gothenburg, Sweden, the following presentation was given as a 20 minute introduction to the use of helium leak detection for container closure integrity testing (CCIT).

Presented on behalf of Leak Detection Associates, the world’s premier manufacturer of custom-built helium leak detection solutions for pharmaceutical, biotechnology, medical device and food packaging clients, the presentation seeks to impart reviewers with an overview understanding of helium leak detection principles of operation, realistic methods for application to pharmaceutical packaging, and case study applications.

Helium gas is a small, nonreactive molecule, making it an ideal tracer for leakage testing, as employed by LDA’s SIMS 1915+ Helium Leak Detector. However, when it comes to preparing samples and subjecting them to a test, there are a range of approaches, each with respective ideal use cases. This presentation aims to illustrate some of the more common ways in which helium leak testing is applied to pharmaceutical packaging such as blisters, vials, and syringes. Reviewed approaches include the sniffer test, filling samples with helium prior to sealing, post-seal helium fill, using LDA’s proprietary vial filler and HSAM, and continuous fill using unique fixtures. Test approaches with reference to ASTM F2391 are discussed.

Important to the message of the presentation are the two case applications presented. The first discusses the application of helium leak testing to vial capping optimization, or assembly validation. In the second case application, an approach for evaluating individual ribs of a plunger is proposed. This type of approach is beneficial to those evaluating inherent integrity or defining their sterile barrier, which has implications for plunger movement during transit. This concept is becoming increasingly relevant as the expansion of prefilled syringe and cartridge-based delivery systems continues.
