All You Need to Know About SIMS 1915+ Low Temperature Package Test Systems

Over the past few decades, the pharmaceutical industry has experienced tremendous growth on a global scale. Assuring the quality of the packaging is of utmost importance to every manufacturer since any defect in the packaging of pharmaceuticals can have major consequences. Pharmaceutical products must be free from microbiological contamination and safe to use from the time of manufacturing until the end of their shelf life. Through contamination in the form of oxygen, humidity, or microbial entry, the stability of the drug may be negatively impacted. Container closure integrity tests with great sensitivity are needed to reduce these risks. Hence, manufacturers choose helium leak detection technology.

Overview of SIMS 1915+

Helium Leak Detection using Seal Integrity Monitoring System (SIMS) 1915+ is a highly sensitive test method for inspecting the integrity of pharmaceuticals to identify leaks. Helium as a tracer gas may be used to quantitatively evaluate packages, providing higher degrees of accuracy than conventional vacuum bubble and dye penetration test methods. This approach makes it possible to compare various package types, sizes, and configurations, as well as manufacturing line settings and storage conditions, throughout the lifespan. LDA SIMS 1915+ is a tried-and-true technique that can be used for a range of package types, including cold form blister cards, foil pouches, parenteral vials, syringes, bottles, pre-filled syringes, and other unique medical devices. It can also be used for package design, tooling qualification, production line setup, and ongoing product quality monitoring.

SIMS 1915+ Low Temperature Add-on Test Systems

In an effort to maintain product quality aspects, complex pharmaceutical and biologic compositions have led to a constant drive towards deeper cold storage. These products, which are frequently protein-based or cell or gene treatments, must be stored in conditions that may include dry ice (-78.5°C) or even liquid nitrogen (-200°C) for storage and delivery.

The packaging system such as screw or crimp cap vials in which the products are enclosed is frequently quite conventional in nature, even if the products necessitating such deep cold storage may be complex. At these temperatures, many of the materials employed in these package systems and responsible for preserving package integrity are not normally evaluated. When subjected to deep-cold or ultra-cold temperatures, elastomeric components in particular may undergo physical changes when materials reach or exceed their glass transition state, resulting in leaks at low temperatures that would not normally be visible at room temperature. This type of leakage is frequently seen in primary seal regions, such as the interface between an elastomeric closure and a glass vial, when the temperature is below -60°C. In order to minimize leakage and demonstrate a deep understanding of a package system's performance in accordance with USP 1207, manufacturers need a method for evaluating container closure integrity while at these low temperatures. This significantly led them to decide on the best package choice and design as well as assembly parameters.

PTI and LDA’s engineering team developed the LT80, or Low Temperature -80°C, Test System, for use with the SIMS range of helium leak detectors to satisfy the market need for analyzing fine leakage at low temperatures. The LT80 system, which incorporates an SP Corporation Chiller, enables simultaneous temperature conditioning, temperature monitoring, and helium leak testing of packages down to -80°C. LT80 combines the recently announced features of the market-leading, Agilent Technologies-based SIMS 1915+ with 21 CFR Part 11 compliant SIMS Software. This is available as an upgrade for current SIMS units in the field or as a complete system. The SIMS 1915+ LT80 package is the first helium leak testing equipment particularly designed for low temperature testing down to -80°C. Sample testing close to -150°C is possible with the LT150 add-on low temperature unit.

LDA (a PTI Company) is the leading global producer of specially designed leak detection systems for pharmaceuticals and medical equipment. LDA’s low temperature add-on systems are ideal for evaluating fine leakage at cold temperatures using Helium Leak Detection Technology.

SIMS 1915+ Helium Leak Detection System and its Applications

SIMS 1915+ Helium Leak Detection System and its Applications

USP <1207> Package Integrity Evaluation of Sterile Products provides an overview of relevant and authorized test procedures that may be utilized to achieve certification criteria. Developing a basic knowledge of these methodologies will allow you to make an informed decision on the most effective test methodology for a specific container and package system. Various CCI test methods are available today. Among them, helium leak testing has proven to be the most chosen method due to its extreme test sensitivity.

Why Use SIMS 1915+ for Leak Detection?

Seal Integrity Monitoring System (SIMS) 1915+ is the perfect choice for a helium-based leak detection system. Using helium as the tracer gas, packages may be quantitatively analyzed to levels much above the vacuum bubble and dye penetration test processes. This quantitative technique supports the entire lifetime by providing direct comparison across numerous packing materials and types, production line settings, and stable storage conditions. SIMS 1915+ can be used for package design, tooling qualification, manufacturing line setup, and continuous product quality monitoring. Each SIMS 1915+ helium leak testing equipment is built to the customer's specifications. SIMS 1915+ can do quantitative CCI analyses on packages with sensitivity as low as 1 x 10 -10 mbar L/s.

What are the Applications of SIMS 1915+?

  • Vials
  • Vials composed of glass and polymer are the most widely used package systems tested using helium leak detection. Vials are provided with a variety of capping to fulfill specific storage or handling needs. Vials are commonly used to store drugs or laboratory samples. Micro leaks in vials that carry sensitive drugs cannot be detected with a visual inspection. Helium leak testing is an ideal method for component qualification for empty components as well as a product-filled vial.

  • Pre-filled syringes
  • The use of pre-filled syringes has increased significantly in the pharmaceutical industry. CCI analyses of pre-filled syringes are more complicated, but they are much more important in ensuring entire system integrity. Helium leak testing for leak detection of pre-filled syringes has proven to be an effective method for evaluating the CCI of pre-filled syringes.

  • Bottles
  • Bottles made of glass or plastic are cost-effective traditional dosage forms ideal for the oral administration of syrups, solutions, and suspensions. Helium leak testing offered by LDA, a PTI company, quickly and effectively tests bottles for leaks and thereby defective bottles can be removed from the production line easily.

  • Blister packs
  • Due to the extreme sensitivity offered, the helium-based test method for evaluating the integrity of a blister card containing solid dose pharmaceutical drugs has been proven to be the most effective approach. Helium remains an ideal test method for qualifying the material components of CFF blister cards.

  • Foil pouches
  • Pharma manufacturers typically use foil pouches when a drug product requires multi-layered packaging. Helium leak testing of foil pouches is a viable and highly sensitive approach to meet strict regulatory requirements.

  • Combination products
  • These are multi-chamber systems that require unique test requirements. Helium Leak Detection as per ASTM F2391 is a well-established and widely used method for testing combination products. Testing combination products using helium leak testing ensure all components meet the strict leak rate requirements.

LDA’s (a PTI company) Seal Integrity Monitoring System (SIMS) 1915+ is an efficient method for a wide range of package types such as pre-filled syringes, cold form blister cards, foil pouches, parenteral vials, and unique medical devices. Seal Integrity Monitoring System (SIMS) Model 1915+ Helium Based Leak Testing System is designed specifically for the needs of the pharmaceutical and medical device industries.
