A rapid, specific, and reproducible high-pressure liquid chromatographic method was developed for the determination of cefoperazone concentration in serum and tissue. The assay uses a simple methanol extraction, with cefoxitin as the internal standard. The limits of detection are 1 to 150 micrograms/ml; the maximum coefficient of variation is 7.4%. Using the same chromatography column, muBondapak phenyl, and mobile-phase 0.005 M tetrabutylammonium buffer-acetonitrile (80:20), the method can be easily adapted for the analysis of cefoxitin and moxalactam.
已开发出一种快速、特异且可重复的高压液相色谱法,用于测定血清和组织中的头孢哌酮浓度。该测定采用简单的甲醇萃取法,以头孢西丁作为内标。检测限为1至150微克/毫升;最大变异系数为7.4%。使用相同的色谱柱(μBondapak苯基柱)和流动相(0.005M四丁基铵缓冲液-乙腈,80:20),该方法可轻松适用于头孢西丁和莫西沙星的分析。
