Organic Acid Columns
Organic Acid Columns
Our BP-OA Organic Acid columns are used for determining the anions of weak organic and inorganic acids. Anions of organic acids include acetate, formate, oxalate and others. Anions of inorganic acids include fluoride, bicarbonate, borate, silicate and others. Acids are eluted usually in order of acid strength with the stronger acids eluting last(in order of increasing pKa values). Retention times of the organic acids may be controlled through adjustment of the eluent pH.

The BP-100, 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.
