USP 621 sets the performance bar, not the part number
USP 621 sets the performance bar, not the part number
2026-10-25
A validated assay that had passed three system suitability runs failed on a Tuesday with a tailing factor of 2.31 against a USP limit of NMT 2.0, and the only thing that had changed since Monday was a new case of column hardware. The method was fine. The column lot was fine. What had changed was the frit porosity on the inlet side, which had shifted from 2 µm to 0.5 µm between lots, and that was enough to change the mass transfer at the head of the bed. That is the kind of event that makes ...

The puncture is a punching operation, and septa behave like sheet metal
The puncture is a punching operation, and septa behave like sheet metal
2026-10-25
A 96-well plate came back from the autosampler with 11 of 96 injections flagged for low area, all clustered in columns 7 through 12, and the injection volume was 5 µL. The septum on that vial lot was 3.0 mm thick, nominal, and the needle was a 23-gauge side-port with a 0.64 mm OD. When I pulled the needle and looked at it under a 10× loupe, the side port had a crescent of white silicone packed into it. That is coring: a plug of septum material punched out, carried into the flow path, and de...

What landed cost actually means for a consumable
What landed cost actually means for a consumable
2026-10-22
I have sat in more procurement reviews than I care to count, and the same scene plays out every time: someone projects a slide showing a 14% unit-price saving on vials and caps, the room nods, and six months later the cost-per-injection figure has gone up. The vial was cheaper. The septa were not the same. The autosampler started missing picks, the QA lab started re-running batches, and the “saving” got eaten by repeat injections and a column that died three weeks early. Landed ...
