title: Determination of ciprofloxacin and its impurities by capillary zone electrophoresis.
abstract: Capillary zone electrophoresis (CZE) has been elaborated for separation, identification and determination of ciprofloxacin and its impurities. The separation, phosphate buffer pH 6.0 was supplemented with 0.075 M pentane-1-sulfonic acid sodium salt. The elaborated method was validated. The selectivity, linearity, limits of detection (LOD) and quantification (LOQ), precision, and accuracy of capillary zone electrophoresis were evaluated. The results obtained by CZE were also compared with those obtained by liquid chromatography. Regarding the validation results the CE method fulfils the current European Pharmacopoeia (Eur. Ph.) requirements. The evaluated CE method could be applicable to the analysis of different medicinal products containing ciprofloxacin.
