BP-100 Pb

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

6% X-Linked poly(styrene/divinyl benzene) (PS-DVB).

The BP-100, Pb column is packed with a 9µ styrene-divinylbenzene polymer resin in the lead form. Complex sugars are often used to add distinctive tastes to foods and beverages. Pentoses and hexoses found in cellulose products are well separated especially glucose, xylose, galactose, cellobiose, arabinose and mannose. This lead resin column is quite useful for the separation of xylose, galactose and mannose which are not completely resolved on the calcium column. In addition, the lead column resolves sucrose and lactose well if these two sugars are present in excess in some samples.
