Effect of Mobile Phase Additive on Enantiomer Resolution for Chiral Amines on Polysaccharide-derived Chiral Stationary Phases by High Performance Liquid Chromatography
Abstract:Chromatographic enantiomer resolution of chiral amines was performed on several covalently immobilized and coated chiral stationary phases (CSPs) based on polysaccharide derivatives under the mobile phase conditions containing base or acid or acid/base additive. The chromatographic parameters including separation factors and capacity factors were greatly influenced by the nature of the mobile phase containing base or acid or salt additive as well as the used CSPs. When 0.05% triethylamine/0.05% trifluoroacetic… Show more
