Columns for Carbohydrate Analysis                 

Benson Polymeric offers a wide variety of columns for the analysis of carbohydrates. All of our columns are packed with polymeric materials, Sulfonated Poly(Styrene-Divinylbenzene), specifically designed to maximize your separation needs. Benson Polymeric columns utilize a variety of separation mechanisms that allow carbohydrates to be separated without the need of gradients. By altering the ionic form of our polymers (calcium, lead, sodium, silver, and potassium) specific carbohydrate mixtures can be separated (see Applications section) by simply using water as your mobile phase.

Another technique Benson Polymeric uses to maximize your separation is to offer a range of cross-linked polymers (see Polymer Description). The degree of cross-linkage determines the porosity of the polymers which can be used to enhance certain separations. Benson Polymeric recommends using column ovens in combination with our columns since the best separations are usually obtained at elevated temperatures (typical range 30 – 90 Celsius).

The BP-800, H carbohydrate column is similar to the ion exchange (2000-0, BP-OA, Organic Acids) column, except for a different degree of cross linking and sulfonation. The variation in cross-linking and sulfonation optimizes not only the separation of carbohydrates present in the sample but also the organic acids and alcohols which may be present. Only dilute acid is used as the mobile phase at ambient temperatures.
