Abstract
A simple and rapid capillary zone electrophoretic (CZE) method was established for separation and determination of chlorphenamin males(CPM), paracetamolum(PAM), and vitamin C(Vc) within 3 min, using borate-phosphate buffer at pH 7.2. The influence of injection time on peak area, peak height and efficiency was studied in detail. The CZE method was successfully applied to quality control of CPM, PAM and Vc in Qiangli Yingqiao containing Vc tablets.
