Twelve different disaccharides and a series of noncyclic malto‐ and cello‐oligosaccharides were used as chiral selectors in capillary electrophoresis (CE). Most saccharides resolved the enantiomers of atropisomeric 1,1′‐binaphthyl‐2,2′‐diyl hydrogen phosphate (BDHP) depending on the type (α or β) and position of the linkage between monosaccharides. The effect of chain length of malto‐ and cello‐oligosaccharides on enantioseparation of BDHP was also investigated. The nature of cations in background electrolytes affected significantly the separation of BDHP enantiomers. Chirality 10:134–139, 1998. © 1998 Wiley‐Liss,Inc.
