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; 25 mM) with sodium dodecyl sulfate (80 mM). The applied voltage was 30 kV 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 50 μm and a total length of 64.5 cm. The detection of target compounds was performed at 200 nm. Under these conditions, a complete separation of cisplatin, carboplatin and oxaliplatin was achieved in less than 10 min. 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.
