A rapid capillary zone electrophoresis method has been developed capable of quantifying 0.05% of R‐enantiomer and assaying the main component in escitalopram formulations. Many parameters influencing enantioseparation were investigated, which include chiral selectors, buffer composition and pH, applied voltage, capillary length, temperature, and rinsing procedure. Optimal separation conditions were...
A chiral capillary electrophoresis method has been developed for the quantification of 0.1% of the enantiomeric impurity (dextrocetirizine) in levocetirizine and determination of both in pharmaceuticals using sulfated‐β‐cyclodextrins (CDs) as chiral selector. Several parameters affecting the separation were studied such as the type and concentration of chiral selectors, buffer composition and pH,...
A rapid method for the enantioseparation of pramipexole and its R‐enantiomer has been developed by capillary electrophoresis. The influence of chemical and instrumental parameters was investigated including the type and concentration of chiral selectors, buffer composition and pH, co‐ions, applied voltage, capillary length and temperature. Optimal separation conditions were obtained using a 50 mM...
