Open and packed gas chromatography columns; includes retention gap columns for focusing liquid samples and guard columns to protect the analytical column from contamination.
Polar column that is suitable for the analyses of solvents, fatty acid methyl esters (FAMEs), food, flavor and fragrance compounds, alcohols, and aromatics.
This non-polar, general purpose column primarily provides a boiling point elution order with a slight increase in selectivity, especially for aromatic compounds.
Porous-layer open-tubular (PLOT) columns are a powerful tool used in gas chromatography for analysis of fixed gases, light hydrocarbons and volatile solvents. They are mostly preferred over traditional columns.
