β-Cyclodextrin has been immobilized on silica gel via a new spacer arm bearing no hydroxyl group. The D-and L-enantiomers of twelve dansylamino acids were separated on the resulting β-cyclodextrin stationary phase by HPLC. Compared with a β-cyclodextrin stationary phase bearing a hydroxyl group on its spacer arm, the new β-cyclodextrin stationary phase exhibited much higher enantioselectivity. The addition of urea (7 M) to the eluent further enhanced the enantioselectivity of all dansyl derivatives except those of leucine, norleucine and phenylalanine.
