Columns for the Separation of Organic Acids
-
USP L17
-
BP-OA, 8% cross-linked resin in the H
+
form
-
Stable pH 0-14
-
Conductivity, UV or RI detection
-
Water or dilute acid eluent
-
For use on biological fluids, beverages, foods, industrial chemicals and
fermentation processes.
Our BP-OA 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.
