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, Sulfonated Poly(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 – 80ºCelsius).

By combining eluent strength, temperature and cross-linkage, Benson Polymeric organic acids analysis columns can separate a wide range of samples (see Retention Times Chart). Please contact technical support at Benson Polymeric and we will help you choose a column for your particular sample.

This rapid alcohol (and carbohydrate) analysis column will separate the more hydrophobic components in the sample giving an accurate determination of the ethanol present. In most cases only minimal sample preparation is required. The undiluted or diluted sample need only be filtered and injected on the column. Use of a short, large diameter, column gives vastly improved peak resolution resulting in high narrow peaks which improve detection limits
