Headspace Carbon Dioxide Partial Pressure in Sample Vials with Microwires at the Stopper-Seal Interface, Both Before (T0) and After (T1) Conducting the Container Closure Integrity (CCI) Test within ∼24 h of Sample Preparation. Values Show the Averages of Five Consecutive Measurements on Each Vial. All Vials with a Liquid Fill Had the Defect in Contact with the Liquid Just Before the CCI Test Was Performed

  • a Leakage was a change ≥ 1 torr between T0 and T1.

  • b PBS is phosphate-buffered saline.

  • c BSA is bovine serum albumin.

  • d One vial confirmed to not be leaking based on leak rate measurements taken after completion of the CCI protocol.
