Container Closure Integrity (CCI) testing helps pharmaceutical manufacturers assess whether packaging protects medicines from leakage and contamination. Packaging formats such as vials, prefilled syringes, and cartridges have different sealing interfaces that require appropriate testing methods.
Quick Answer : Life science services help manufacturers tailor CCI test methods to specific packaging systems and verify their suitability through performance evaluation under defined testing conditions.
What are CCI Method Development and Validation?
CCI method development involves selecting a suitable test method for a specific container closure system. The selection depends on package design, required detection sensitivity, and testing conditions.
Method validation evaluates whether the selected method consistently meets its intended purpose under defined conditions.
These activities are important for pharmaceutical products such as biologics, vaccines, and injectable medicines packaged in vials, prefilled syringes, and cartridges. Each packaging format has different sealing interfaces that must be considered during testing.
How Do Life Science Services Support CCI Method Development?
Quick Answer : Life science services help manufacturers determine the testing approach based on package design, sealing characteristics, and product-specific requirements.
1.Evaluating Packaging Requirements
The container design, closure system, and storage conditions are reviewed before selecting a test method. This helps identify potential leak paths and determine the appropriate test setup.
For example, a vial stopper and a syringe plunger have different sealing interfaces. The testing procedure must account for these differences.
2. Selecting a Suitable Test Method
The selected method should match the packaging system and its testing requirements. Helium leak testing is suitable for applications that require quantitative leak-rate measurements.
During testing, helium acts as a tracer gas. A mass spectrometer detects helium passing through a leak path under defined test conditions.
PTI’s SIMS 1915+ Technology supports this process by detecting helium and measuring leak rates. Its published specification reports sensitivity levels as low as 1 × 10?¹° mbar·L/sec. Actual performance depends on the package, test configuration, and application.
3. Establishing Test Parameters
The testing procedure must be developed for the selected package and equipment. Important parameters may include:
- Helium concentration and test pressure
- Sample preparation and fixture design
- Test duration and equipment settings
- Required detection sensitivity
- Temperature and other relevant test conditions
