HPLC Separation of Carboxylic Acids Chromatogramm

HPLC separation of carboxylic acids (nicotinic acid, benzoic acid and acetylbenzoic acid) on Primesep B2 column using an isocratic method by reverse-phase and anion-exchange mechanisms. The elution of carboxylic acids using the same isocratic method and mobile phase can be reversed by using a reverse-phase cation-exchange mechanisms of the Primesep 100 column. The mobile phase is water, acetonitrile (MeCN, ACN) and formic acid with a UV detector.
