Popis: ( S )-Naproxen-derived and (3 R ,4 S )-Whelk-O chiral stationary phases (CSPs) were immobilized on 3 μm silica supports and packed into 100 μm I.D. fused-silica capillaries. Enantiomers of some neutral analytes representing a variety of different classes of compounds were separated by electrochromatography using 2-(N-morpholino)ethanesulfonic acid modified with acetonitrile as the buffer system. High column efficiency (up to 200 000 plates per meter) and substantial levels of enantioselectivity were obtained in all cases with separations usually being performed in less than 10 min.
