Techniques such as H.P.L.C. (High Performance Liquid Chromatography) and G.C. (Gas Chromatography) use columns - narrow tubes packed with stationary phase, through which the mobile phase is forced.

Gas chromatography (GC) and other chromatography equipment is now available to order from the Cole-Parmer Instrument Catalog. Click below gas chromatography category to view all list of brands.

Gas chromatography is used to describe the group of analytical separation techniques used to analyze volatile substances in the gas phase. In gas chromatography, the components of a sample are dissolved in a solvent and vaporized in order to separate the analytes by distributing the sample between two phases: a stationary phase and a mobile phase.
