Carboxen Adsorbents - Merck Supelco Sigma-Aldrich

Carboxen GC columns from Merck Supelco are based on carbon. These adsorbents have increasingly smaller (tapered) pores. This results in increased thermodynamic and kinetic efficiency for both adsorption and desorption. The surface chemistry of these materials can also be adapted to specific analytes. As a result, there are 19 different Carboxen materials, three of which (Carboxen 1000, 1006 and 1010) are used in GC columns.
