Cutting Fused Silica Capillary Columns per LC-GC Application Note September 30 2016

Polymicro Technologies (a division of Molex) was the first company to mass produce fused silica capillary for the entire capillary gas chromatography market. That was thirty years ago and they are still the single largest manufacturer of the materials. (Polyimide coated, fused silica capillary for GC columns was an HP invention, but they reserved their production for themselves, alone.) Polymicro has made more GC capillary than anyone on the planet, by far:...

Instructions: IQ’s Sapphire™ Wafers for Cutting GC Capillary Columns September 30 2016

Cutting capillary and making gas-tight seals is critical to good GC practice and making seals on silica press-fit connectors requires almost perfect cuts (unless you are using Pres2fit™ connectors). Cleanly cut ends are also important for CE for minimizing distortions of the electric field at the column ends.  Capillary: The first thing that the separation scientist needs to understand is that not all silica capillary is the same. There are...
