Leak detection: A guide to new packaging validation with helium mass
Helium mass spectrometry has emerged as the new leak detection standard for non-porous packages such as vials, syringes, and cartridges. The method is favoured by manufacturers and regulators for its higher sensitivity, faster test times, and traceability, as well as the determinism it offers in contrast to the probabilistic traditional methods.
THE ESSENTIAL GUIDE TO VACUUM LEAK DETECTION
1x10-6 mbar*l/s is with a helium leak detector (HLD). The most accurate and rapid leak detection methods employ helium as the tracer gas, coupled with a mass spectrometer for identification and quantification typically to minimum detectable leak of 10-12 mbar*l/s. The reasons for using helium (mass M = 4) for leak detection are compelling: it
Leak Testing: Guide to helium leak testing
There are 2 basic techniques; high vacuum testing which allows leak test thresholds to be set down as low as 1x10 -12 mbar.l.sec -1, or sniffing which is generally used for helium leaks down to 1x10 -6 mbar.l.sec -1. For reference 1 cubic millimetre per second is approximately 1x10 -3 mbar.l.sec -1. or 1cc is approximately 1mbar litre per second.
