Four polymers cover 95% of the market, and each fails in a specific way

A 12-position run on a Shimadzu GC-2010 came back with siloxane peaks at m/z 73, 147, 207, and 281 in three of twelve blanks. The septa were silicone, 11 mm, 3 mm thick, and the inlet was running at 280 °C. The lot had been in service for four days. Every blank injected after the fourth day showed the same three-peak train, and the bleed got worse with each subsequent injection. That is not a septa quality problem. That is a material selection problem: silicone at 280 °C in an inlet that se...

Set the reorder point from lead-time variance, not from a round number

A buyer called me in March because her 9 mm screw-thread vial order had slipped three weeks and her LC-MS batch was down to 11 vials. The root cause was not the vial. It was a reorder point set at 200 units against a consumption rate of 480 per week and a supplier lead time that had drifted from 4 weeks to 7. She had been reordering at 200 for two years because that number “felt safe” when volumes were lower. Three weeks of cover against a seven-week lead time is not safety stoc...

What each molding process can actually hold on a 2 mL vial

A 2 mL clear glass vial that mics at 11.98 mm on the outside diameter can still jam a 12-position autosampler tray if the same lot measures 12.06 mm at the shoulder, and that is the call I got on a Tuesday morning after 340 injections had run clean. The instrument was fine. The tray was fine. The chromatography vial lot had drifted 0.04 mm on a dimension nobody was charting. That is the whole argument for treating chromatography vial dimensional tolerance capability as a process property, n...

SW-846 barely specifies the vial, and that is the trap

The auditor asked for the vial lot number before she asked for the calibration curve. That was the whole visit, really. We had run Method 8260C volatiles for eleven years, and the first document pulled during the EPA method audit was a receiving log showing which case of 40 mL vials went into the batch that produced a failed 5% relative standard deviation on the internal standard area. The vial was never on the method’s list of critical supplies. It was on the auditor’s list fro...
