Capillary Zone Electrophoresis of Organic Acids and Anions

Abstract
Two buffer systems are described for the separation of anions by capillary electrophoresis. In each system, the ions are monitored by indirect detection. Organic acids are separated with potassium hydrogen phthalate, 2-(N-morpholino)-ethanesulfonic acid and tetradecyltrimethyl ammonium bromide. Other anions are separated in 1,2,4,5 benzene tetracarboxylic acid (pyromellitic acid) and diethylenetriamine.
