title: [Evaluation of the quality of mexiletine hydrochloride using capillary electrophoreses].
abstract: Mexiletine hydrochloride and its potential impurity xylenol were determined by micellar electrokinetic chromatography in a 25 cm long capillary. The effect of parameters--temperature, electric field, concentration of analyzed compounds, type and composition of background electrolyte--on the separation of analytes and precision of analysis was studied. The advantage of the elaborated method is a very short time of analysis (2.3 min) at the sufficient level of precision and reliability of results.
