Beyond The Instrument: How To Build A Defensible CCIT Method Selection Strategy

By Christian Collazo-Sarra, Manager, Container Closure Integrity, Drug Delivery, and Package Testing, Pace® Life Sciences

Choosing a container closure integrity testing (CCIT) method requires looking beyond instrument availability or baseline sensitivity claims. A truly defensible strategy begins by identifying product-specific risks, establishing the target defect size, and determining the maximum allowable leakage limit (MALL).

Evaluating deterministic technologies—such as vacuum decay, high-voltage leak detection, helium leak detection, and laser-based headspace analysis—against probabilistic options like dye ingress ensures the chosen approach matches the specific container closure system, product characteristics, and lifecycle stage. By systematically evaluating factors like physical state, conductivity, optical clarity, and practical testing constraints, manufacturers can establish scientifically justified testing protocols. This risk-based framework bridges the gap between raw analytical capability and regulatory expectations, ensuring long-term product quality and patient safety.
