Gas Chromatography Columns

Gas chromatography (GC) columns facilitate the separation and analysis of various compounds through vaporization. Such tools are used in many industries, including pharmaceutical, food, and forensics. In GC, in which a gaseous mobile phase traverses through a liquid or solid stationary phase, columns are generally constructed of glass or metal tubing. When selecting a suitable column for this method, functional groups and polarity of the sample must be considered. In addition, the use of a guard column can protect the main column from contamination, extending its lifespan. Browse the GC columns below and visit the supplier page for more information.
