Quality control of pharmaceutical formulations containing cisplatin, carboplatin, and oxaliplatin by micellar and microemulsion electrokinetic chromatography (MEKC, MEEKC)

|Abstract||A micellar electrokinetic chromatography (MEKC) method was developed for the determination of cisplatin, carboplatin, and oxaliplatin in pharmaceutical formulations. The background electrolyte consisted of a phosphate buffer (pH 7.0; 25mM) with sodium dodecyl sulfate (80mM). The applied voltage was 30kV and the sample injection was performed in the hydrodynamic mode. All analyses were carried out in a fused silica capillary with an internal diameter of 50μm and a total length of 64.5cm. The detection of target compounds was performed at 200nm. Under these conditions, a complete separation of cisplatin, carboplatin and oxaliplatin was achieved in less than 10min. The MEKC-UV method was validated and trueness values between 99.7% and 100.8% were obtained with repeatability and intermediate precision values of 0.7-1.4% and 1.1-1.7%, respectively for the three drugs. This method was found appropriate for controlling pharmaceutical formulations containing platinum complexes and successfully applied in quality control at the Geneva University Hospitals.|
