Why septa fail more often than any other consumable
Last month a QC analyst called me because her GC run had developed a split peak on the solvent front and a retention time drift of about 0.04 minutes per injection. We spent two days checking the column, the inlet liner, and the carrier gas traps before I asked the obvious question: how old is the septum? She pulled the inlet apart and the septum had a visible coring hole, a doughnut-shaped depression, and a small tear at the 4 o’clock position. That single part, worth about forty cen...

Why septa fail in normal daily use
I have watched a lot of septa fail in ways that had nothing to do with the septum itself. A lab calls and says the septa are bad because the GC is showing ghost peaks, or the HPLC is losing pressure, or the autosampler is coring needles. Nine times out of ten, the septum is doing exactly what the wrong septum does in that application. The rest of the time it is damaged on installation, over-torqued, run past its temperature rating, or punched far more times than the material can survive. Th...
