Septa ghost peaks are material chemistry, not method drift
A 30 m × 0.25 mm × 0.25 µm GC column that had run clean for eleven months suddenly showed a 0.8 pA rise in FID baseline between 200 °C and 280 °C, plus three repeatable peaks at retention times matching nothing in the method. The integrator flagged them at 0.4 to 1.1 area counts. A solvent blank injected through the autosampler reproduced all three peaks; the same solvent injected through a manual syringe port on the same inlet did not. That single comparison isolated septa ghost peaks, ext...

Set the reorder point from lead-time variance, not from average lead time
Last March a 48-position autosampler rack ran dry at 4:12 a.m. because the buyer had set the septa reorder point at “one case” and nobody noticed the case was three weeks late. The line had been consuming 340 septa a week, the distributor’s quoted lead time was 10 working days, and the actual delivery on the previous four POs had averaged 19 days. That gap between quoted and actual is the whole reason septa MOQ, lead time, and reorder point planning deserves its own spread...

What each moulding process can actually hold on a septum
Last spring a customer sent back three lots of 11 mm moulded septa because their autosampler was throwing N=12 “no vial detected” errors on roughly 4% of injections. The septa were within the print on every dimension I could measure with a 0.01 mm micrometer. The problem was a 0.18 mm difference in the thickness at the centre versus the rim, invisible to a two-point check, and it was enough to lift the vial cap off the transport arm on a specific Shimadzu rack. That is the reali...
