Enantiomeric separation of three chiral drugs by nonaqueous capillary electrophoresis with triethylamine as additive

The enantiomeric separation of chiral drugs by capillary electrophoresis (C E) in nonaqueous system has been investigated. Successful separation of bep ridil, ondansetron and pinacidil in formamide using beta-cyclodextrin as ch iral selector were achieved. The addition of triethylamine into the backgro und electrolyte enhanced the enantiomeric discrimination.
