What coring actually is, mechanically
I still remember the Monday morning when a client sent back a batch of GC results with a single line: “Why do we keep seeing ghost peaks at 14.2 minutes, and why does the autosampler needle look like it’s been chewed?” I pulled the septum from their inlet, held it up to the light, and there it was. A perfect little cone of silicone sitting in the injection port, and a needle with a burr you could feel with a fingernail. That’s the coring problem in a nutshell. It doe...

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...
