HPLC Separation of Isomers of Aminobutyric Acids

Primesep C separates the isomers of aminobutyric acids by a combination of reversed-phase and ionic interaction mechanisms. alpha-Aminobutyric acid, beta-Aminobutryic acid, and gamma-Aminobutyric acid (GABA) are baseline resolved without ion-pair reagents. The HPLC separation uses a mobile phase of water, acetonitrile (MeCN, ACN) ammonium acetate with evaporative light scattering detection (ELSD).
