Two mixtures of neutral cyclodextrins (CDs) were used in Electrokinetic Chromatography (EKC) to model and optimize the simultaneous enantiomeric separation of a group of seven drugs. Heptakis(2,6-di-Omethyl)-β-CD (DM-β-CD) combined with methyl-γ -CD (M-γ -CD) or with carboxyethyl-γ -CD (CE-γ -CD) was employed in a 25 mM formate buffer at pH 3.0 to have the drugs studied positively charged. |
