General description

Application: This column is ideal for the separation of all major components in permanent gas (helium, hydrogen, oxygen, nitrogen, carbon monoxide, methane, and carbon dioxide) and light hydrocarbons (C2-C3) in the same analysis. It is the only column commercially available that is able to separate all major components in permanent gas. This column can also separate oxygen from nitrogen at subambient temperatures. USP Code: None Phase: Carbon molecular sieve Temp. Limits: Subambient to 250 °C (isothermal or programmed)

Carboxen^® Adsorbent is ideally used for solid-phase microextraction (SPME) and does highly efficient extraction of small polar molecules from aqueous solution. Porous-layer open-tubular (PLOT) columns are a powerful tool employed in gas chromatography during analysis of fixed gases, light hydrocarbons and volatile solvents. They are mostly preferred over traditional packed columns.
