Abstract
A comparative study of enantioseparations was performed in capillary liquid chromatography (CLC) and capillary electrochromatography (CEC). Cellulose tris(3,5-dichlorophenylcarbamate) (CDCPC) was used as stationary phase in c ombination with nonaqueous liquid phases. Laser light scattering and scanni ng electron microscopic techniques were used in order to characterize the p acking material. Van Deemter curves were plotted and the A, B, and C coeffi cients were calculated in order to determine the contribution of the variou s band-broadening increments of the plate height in CLC and CEC.
