Dependence of chiral separations on the amount of cyclodextrins as selectors, employing the partial filling technique in capillary zone electrophoresis
A. Amini et al., Dependence of chiral separations on the amount of cyclodextrins as selectors, employing the partial filling technique in capillary zone electrophoresis, CHROMATOGR, 51(3-4), 2000, pp. 226-230
The enantioselectivity, resolution factor and migration times for some loca
l anaesthetic drugs were evaluated at different selector concentrations and
plug lengths with different cyclodextrins as chiral selectors using the pa
rtial filling technique. The resolution remained constant when equal amount
s of the chiral selector at a concentration below the optimal concentration
were introduced in the capillary. However, the selectivity factor increase
d with increasing concentration of the chiral selector.
