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.
Use a glass column for applications where high inertness is required, such as for the analysis of active analytes. All glass columns undergo a proprietary high temperature silanization to ensure inertness.
An economical metal column should be used for less demanding applications where the inertness of glass is not required. This column is of a general configuration, and can be carefully bent to fit most instruments.
Kits include one cartridge, a stand-alone holder, a piece of tubing, and 2 nuts and ferrules. Guard cartridges require holders that are sold separately.
