Abstract


In this study, analyses were carried out in a fused-silica capillary (i.d. 50.0 µm, total length 48.5 cm and effective length 40.0 cm), in normal mode, applying a voltage of 20 kV. Sample injections were made in a hydrodynamic mode over 7 seconds under a pressure of 50 mbar. Capillary temperature was set at 35 °C and the detection was performed at 205 nm wavelenght. Background electrolyte was 40 mM citrate buffer at pH 6.0 and the internal standard was labetalol HCl. Total analysis time was shorter than 5 minutes. The method was validated according to the ICH guidelines and it was found to be linear, precise, accurate, specific, robust and rugged. Linearity range was found to be 1.0 – 60.0 µg mL-1 and the limit of detection and quantitation were found as 0.5 and 1.0 µg mL-1, respectively.
