Abstract
Capillary zone electrophoresis was employed for the determination of clozapine using an end-column amperometric detection at a carbon fiber array microdisk electrode with simplified capillary/electrode alignment. The optimum conditions of separation and detection are: Britton-Robinson buffer, pH 2.0 (1.3 x 10(-2) mol/L total concentration of acids, 3.2 x 10(-3) mol/L NaOH), 15 kV for separation voltage, 5 kV and 10 s for injection voltage and injection time, respectively. The limit of detection is 4.2 x 10(-7) mol/L or 1.2 fmole (signal to noise, S/N = 2). The relative standard deviation is 1.4% for the migration time and 2.5% for the electrophoretic peak current. The method was applied to the determination of clozapine in human blood. The recovery of the method is between 94-104%.
