REGULARITIES OF RETENTION AND SEPARATION OF STEREOISOMERS OF DIPEPTIDES ON ENANTIOSELECTIVE STATIONARY PHASES WITH GRAFTED ZWITTERIONIC CHIRAL SELECTORS
The regularities of the separation of stereoisomers of dipeptides on two new non-commercial chiral stationary phases, ZWIX (+A) and ZWIX (-A), with grafted zwitterionic selectors obtained by chemical modification of quinine and quinidine were studied. Water-methanol solutions were used as the mobile phase. The possibility of separating stereoisomers of some dipeptides was shown. The effect of the composition of the mobile phase on retention and separation was studied.
