Chankvetadze et al. have demonstrated the potential of flow-counterbalanced capillary electrophoresis (FCCE) in chiral and achiral micropreparative separations [27], Unlimited increase of separation selectivity can be achieved for binary mixtures, such as (+ )-chlorpheniramine with carboxymethyl-(3-cyclodextrin chiral selector, or a- and (3-isomers of a asparatame dipeptide. The carrier of the chiral selector or pseudo-stationary phase, electroosmotic flow (EOF), pressure-driven flow, or hydrodynamic flow can be used as a counterbalancing flow to the electrophoretic mobility of the analyte or vice versa, resulting in dramatic changes of the effective mobilities of the sample mixture components [28], This approach can be used for micropreparative CE, stepwise separations, and fraction collection of multicomponent mixtures [27],...

Another promising mode of chiral CE separations seems to be the mobility-counterbalanced mode [15, 29-39]. Counterbalancing of analyte electrophoretic mobility by pressure has been applied by Culbertson and Jorgenson [29] for the enhancement of the detection sensitivity in achiral CE. Later the same technique was used for the separation of isotopomers of phenylalanine [30]. The potential advantage of flow-counterbalanced capillary electrophoresis (FCCE) can be seen fromEq.
