By means of gas chromatography (GC), the analysis of gaseous or highly volatile substances which can be evaporated completely without undergoing decomposition is possible. Due to different boiling points and distribution in the stationary phase (liquid film or solid), the analytes can be separated. You will find all commonly used capillary columns, as well as custom-made packed columns and all common separation columns for gas chromatography. we offer over 10,000 different capillary columns including columns of all major manufacturers. Packed columns are available upon request. Compare columns from different manufacturers by making use of our very own GC Column Configurator.
