To ensure patient safety, pharmaceutical products must be kept properly packaged prior to use. Proper packaging prevents ingress of contaminants. Unfortunately, these contaminants are not always visible to the human eye and container closure integrity (CCI) tests must be performed to ensure the package has not been compromised. One way to test for proper CCI is to analyze the headspace gas composition of the vial.
This article describes how CCI of a vial can be determined using Headspace Gas Ingress Methods.
