Fill volume sets the pressure budget before the septum does
A 10 mL headspace vial filled to 6 mL with a 20 mm butyl septum and a 20 mm aluminium crimp will start leaking helium at the seal after roughly 40 to 60 autosampler punctures with a 23-gauge needle, not the 100 the vendor’s generic puncture count suggests. I know this because I watched a stability batch fail that way: the run had 48 injections on the same vial, the internal standard area RSD climbed from 0.9% to 4.7% between injection 30 and injection 44, and the leak was at the septu...

If you are buying septa at volume and ...

Pick the AQL before you pick the sample size, not after
A lot of 3,000 11 mm grey butyl septa left the moulding floor on a Tuesday and reached the customer’s incoming dock on Friday with a Certificate of Conformance that said “meets specification.” By the following Wednesday, the customer’s QC group had rejected the lot: 14 of 200 sampled closures leaked at 1.5 bar helium, and 9 showed visible flash across the needle path. The supplier had no septa AQL sampling plan at all. They had a visual check by the line operator and...
