GL Sciences offers a variety of GC columns, categorized by regulations like the United States Pharmacopeia (USP) which uses codes such as G1 (Dimethylpolysiloxane oil) and G3 (50% Phenyl - 50% methylpolysiloxane). Columns are described by their stationary phase, including different types like phenyl-methylpolysiloxanes (InertCap 17) and polyethylene glycols (InertCap Pure-WAX). There are also different column types beyond those in regulations, such as amine, fast GC, and standard capillary columns.
