Chiral Separation by Capillary Electrochromatography Using Cyclodextrin Phases

electrochromatography (p-CEC); and (iii) rod-CEC. In o-CEC, the internal capillary wall is coated with the chiral stationary phase (see Fig. 1 ), e.g., with Chirasil-Dex (see Fig. 2 ), which is a permethyl-β-cyclodextrin covalently linked via a spacer

Gas-Chromatographic Enantioseparation of Unfunctionalized Chiral Hydrocarbons: An Overview

of the hydrocarbons, enantiorecognition in the presence of cyclodextrins is ascribed to weak van der Waals forces. Thermodynamic parameters of enantiorecognition between four chiral alkanes and octakis(6-O -methyl-2,3-di-O -pentyl)-γ-cyclodextrin (Lipodex G

Cyclodextrin-Mediated Enantioseparation in Microemulsion Electrokinetic Chromatography

here sulfated β-cyclodextrin was successfully applied. The method is appropriate to resolve an entire series of chiral phenethylamines and can be used for separation of the racemates and impurity profiling, e.g., the determination of the enantiomeric excess.
