J&W PLOT GC Columns are ideal for separating compounds that are gases at room temperature.

Porous Layer Open Tubular (PLOT) GC Columns are the ideal Gas Chromatography (GC) columns for the analysis of light hydrocarbons and fixed gases. PLOT solid-gas chromatography columns are used for separations of small molecules. Protect your Gas Chromatograph from PLOT column shedding with the J&W PLOT particle trapping technology to avoid common particle trap challenges, including particle accumulation, leaks and flow restriction, while also saving time.
