In this study, liquid chromatographic enantiomer resolution of N-protected α-amino acid was performed on a covalently immobilized chiral column based on polysaccharide derivative under reversed and normal-phase conditions. The effect of the reversed mobile phase on the chromatographic parameters of the enantioselectivities, resolution factors and retention times using the covalently immobilized was shown. Also the enantiomer separation of N-protected α-amino acid in the reverse and normal phase was compared and the results obtained in aqueous acetonitrile solution of the former mobile phase were generally lower than those in the latter mobile phase. However, the enantioselectivities obtained in aqueous methanol solution of the reversed mobile phase were higher than those in the normal mobile phase.
