Differential migration concept

More recently, capillary electrochromatography (CEC) has been adapted for enantioseparation concepts. In this separation method, the driving force for solute transport through the capillary columns is the electroosmotic flow (EOF) in addition, for charged SAs, an electrophoretic transport increment has also to be considered. The enantioseparation occurs due to differential distribution of the SA-enantiomers to the immobilized chiral SO moieties, or in the additive mode due to differential migration of diastere-omeric SO-SA a.ssociates and/or their differential distribution onto an achiral stationary phase. Thus, the following strategies have been adopted for CEC enantioseparations,... [Pg.435]
