Set the reorder point from the demand distribution during lead time, not from

Last spring a QC lab running 240 injections a week on a single GC called me because they had run out of 2 mL clear crimp vials on a Thursday afternoon. The purchasing manager had set the reorder point at one week of cover, the distributor’s quoted lead time was five business days, and the last shipment arrived on day nine. That gap cost them a 22-hour instrument idle and a rescheduled batch release. The fix was not a bigger order. It was a reorder point built from lead-time variance, ...

Where the vapor actually leaves a sealed vial

A 96-position autosampler run on a 2 mL crimp vial lost 3.8% of its acetonitrile volume over 18 hours in a 4 °C tray, and the internal standard peak area drifted 11% low by the last injection. The analyst blamed the column. The column was fine. I weighed the vials before and after the run and the mass loss pointed straight at the seal. That is the kind of aijiren seal failure, evaporation and sample loss problem that never shows up as an error code. It shows up as drift, and drift gets misd...

A tested value has a method, a sample size, and an acceptance limit attached

A lot of 2 mL clear glass vials came back from a stability lab last spring with a complaint I had not seen before: septum coring counts on the same batch ranged from 3 to 11 punctures before a visible plug appeared, tested on the same autosampler with the same 22-gauge needle. The datasheet said “puncture resistance: ≥10.” That number was real. It was also nominal, measured on a molded reference plug at 23 °C, not on the die-cut lot we shipped. The gap between what a sheet guara...
