General-purpose and application-specific capillary (open) columns in various lengths, diameters, particle sizes, and temperature ranges; includes retention gap columns and guard columns.
For less demanding applications where the inertness of glass is not required, choose more economical stainless steel. Column can be carefully bent to fit most instruments.
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.
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.
