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.
