Drug analysis of cefoperazone sulbactam sodium

Cefoperazone sulbactam sodium was analyzed using a Kromasil C18 column (5 µm, 150 × 4.6 mm). The chromatographic separation was carried out under the following conditions: the mobile phase consisted of 0.005 mol/L tetrabutylammonium hydroxide in water and acetonitrile in a ratio of 75:25 (v/v). The detection wavelength was set at 220 nm to ensure optimal sensitivity for the compound. The flow rate was maintained at 1.0 mL/min throughout the analysis to achieve good resolution and reproducibility. This method is suitable for the quantitative determination of cefoperazone sulbactam sodium in pharmaceutical formulations. The column efficiency and peak symmetry were monitored to confirm the reliability of the results. All parameters were optimized to provide accurate and consistent chromatographic performance. The method is simple, fast, and well-suited for routine quality control analysis.
