Supelco offers several types of polymeric based columns, SUPELCOGEL, for the analysis of carbohy­drates, organic acids, and alcohols. The optimum choice of column is typically a combination of peak resolution, analysis time and value. Below is summary of the different types of column choices:

SUPELCOGEL columns are packed with sulfonated (strong cation) polystyrene-divinylbenzene co-polymers. These PS-DVB based columns are chemically stable and extremely reliable. In order to maximize the separation of the different types of samples common to the industries we serve, SUPELCOGEL utilizes two variations of the PS-DVB co-polymer (6%, and 8% cross-linked). These two base polymers are functionalized into different ionic forms to further enhance the separation of spe­cific samples.
