Separation of optical isomers of amino acids on modified chitin and chitosan layers

Biomed Chromatogr. 1997 Sep-Oct;11(5):272-5. doi: 10.1002/(SICI)1099-0801(199709)11:5<272::AID-BMC695>3.0.CO;2-V.

Abstract

The possibilities of separation of seven D,L-mixtures of amino acids on chitin, chitosan beds and their modifications are tested, using TLC methods. From investigated stationary phases chitin modified by Cu2+ ions may be used for separation of optical isomers of amino acids. The best results have been obtained in chromatographic systems with ternary mobile phases.
