Separation columns for gas chromatography

By means of gas chromatography (GC), gaseous or highly volatile substances which can be evaporated completely without undergoing decomposition, can be analyzed. The analytes can be separated by different boiling points and distribution in the stationary phase (liquid film or solid). In our product range, you will find not only the commonly used capillary columns, but also custom-made packed columns and all common separation columns for gas chromatography. Among the more than 10,000 different capillary columns, you will find the columns of all major manufacturers such as Agilent, SGE, Thermo Scientific and Vici. Packed columns are available upon request. If you want to compare different manufacturers and columns, you can use our GC column configurator.
