Open and packed gas chromatography columns; includes retention gap columns for focusing liquid samples and guard columns to protect the analytical column from contamination.
Capillary GC column is also known as open tubular column. The carrier gas flows through the central aperture and is unrestricted throughout the length of the column.
SP™-2331 GC column maybe used in high-resolution gas chromatography, with mass selective detection for the analysis of polychlorodibenzodioxins and polychlorodibenzofurans with 1 to 8 chlorine substituents.
Non-polar general purpose column provides primarily a boiling point elution order with a slight increase in selectivity, especially for aromatic compounds.
