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, SulfonatedPoly(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 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. 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 – 90ºCelsius)

COLUMNS FOR ORGANIC ACID ANALYSIS

Benson Polymeric offers a wide variety of columns for the analysis of organic acids. All of our columns are packed with polymeric materials, SulfonatedPoly(Styrene-Divinylbenzene), specifically designed to maximize your separation needs. Benson Polymeric organic acid analysis columns primarily utilize ion-exclusion as the separation mechanism. Using a simple acid mobile phase (typically dilute sulfuric acid), a wide variety of organic acids can be separated without the need of a gradient. By altering the concentration of the acid mobile phase, organic acid separations can be maximized for your particular sample.

Another technique Benson Polymeric uses to maximize your separation is to offer two types of cross-linked polymers (see below). The degree of cross-linkage determines the porosity of the polymers which can be used to enhance certain separations. Benson Polymeric also recommends using column ovens in combination with our columns since the best separations are usually obtained at elevated temperatures (typical range 30 – 80º Celsius).
