Evaluation of the Quality of Mexiletine Hydrochloride by Means of CapillaryElectrophoresis
- Slovakofarma, a. s., Hlohovec
Mexiletine hydrochloride and its potential impurity xylenol were determined by micelar electrokinetic chromatography in a 25 cm long capillary. The effect of parameters - temperature, electricfield, concentration of analyzed compounds, type and composition of background electrolyte - on theseparation of analytes and precision of analysis was studied. The advantage of the elaboratedmethod is a very short time of analysis (2.3 min) at the sufficient level of precision and reliabilityof results.
Keywords: mexiletine hydrochloride; xylenol; separation; determination; micelarelectrokinetic chromatography.
