Chiral separations of amino acids using di- and tri-peptides for zwitter-ion pair chromatography.
Separations of tryptophan enantiomers by zwitter-ion pair chromatography using small peptides as ion-pairing agents have been studied with emphasis upon the nature of the peptide, the mobile phase composition, and the nature of the chromatographic support. In addition, this procedure has been extended successfully to two other amino acids.
