Understanding Combination Products Leak Detection Using SIMS 1915+

Understanding Combination Products Leak Detection Using SIMS 1915+

Food and Drug Administration (FDA) requirements for drug testing of combination products are strict. Companies seeking FDA clearance for such products must fully understand the requirements for FDA approval in order to prevent costly and time-consuming errors. Combination products are made up of two or more regulated components, such as pharmaceuticals, devices, or biologicals, that have been physically, chemically, or otherwise combined and formed as a single entity to achieve a therapeutic effect. A combination product can combine at least two of these product categories, and sometimes all three. Traditional drug-device combination products, such as a syringe pre-filled with a drug, auto-injectors containing a filled cartridge and needle, and co-packaged or kitted products, are some of the most common types of combination products.

The constantly increasing demand for combination pharmaceutical products continues to fuel innovation and creates numerous interesting opportunities that will provide the medical community with promising new alternatives for improving patient care and results. However, bringing bio/pharmaceuticals and medical devices together to form a combination product necessitates extensive testing of all product ingredients.

Why Use SIM 1915+ for Leak Testing Combination Products?

A Helium-based leak detection system-Seal Integrity Monitoring System (SIMS) 1915+ is an excellent solution for detecting leaks in combination products. Packages may be quantitatively evaluated using helium as the tracer gas, which assures better levels of accuracy when compared to traditional vacuum bubble and dye penetration test procedures. SIMS 1915+, which has been proven to be an effective leak detection approach, may also be utilized for package design, tooling certification, manufacturing line setup, and ongoing product quality monitoring. LDA custom builds each SIMS 1915+ Helium Leak Testing device to customer specifications. Cold form blister cards, foil pouches, parenteral vials, syringes, pre-filled syringes, and unique medical devices can also be tested using SIMS 1915+.

Technology Overview

SIMS Model 1915+ helium-based leak testing system offered by LDA ( a PTI company ) is specifically designed for medical and pharmaceutical package leak detection. The SIMS 1915+ enables quantitative analysis of package systems at sensitivity levels as low as 1 x 10 -10 cc/s at room temperature. The Helium Leak Detector Module (HLDM), the most crucial component, is built within a Console Frame Assembly with a Stainless Steel working surface and an optional Dual Test Port Manifold. The consoles have a locking wheel and an articulating arm system for attaching the computer and peripherals, making the independent device simple to operate and maneuver.

The SIMS 1915+ Leak Detection System specs and add-on components are shown below.

  • Helium Leak Detector Module (HLDM): Oil-Free, Production Version in Console Frame Assembly with Stainless Steel Working Surface and Dual Test Port Manifold.
  • Vacuum Test Fixture Model (VTFM): a custom-made fixture for testing vial container samples.
  • Head Space Analyzer Module (HSAM): Model VM-2 that includes three (3) Puncture Probes (two spares) for determining the concentration of helium in the headspace of vial containers.
  • Integral Calibration Chamber (with Calibrant Gas Flow Meter/Controller) for HSAM Calibration and a Universal Holder for various vial diameters are offered.
  • Helium Filling Device designed specifically for vial testing sample prep that allows vials to be filled with helium.
  • Low Temperature (LT) Add-on devices created particularly for evaluating products in ultra-cold storage temperatures as low as –140 °C.

SIMS 1915+ Applications

Common applications of SIMS 1915+ include:

  • Pre-filled syringes
  • Vials
  • Bottles
  • Combination products
  • Foil pouches
  • Blister packs

Combination products provide a safe, effective, and convenient method of administering the drug or biologic therapies. The purpose of testing combination products is to obtain information to support the claim that all use-related hazards connected with the product have been reduced to the greatest extent possible. LDA is well-versed in the extensive testing requirements and regulatory criteria for bio/pharmaceutical products and medical devices, and provides complete testing services for these components, both individually and in combination.
