【摘要】 目的:建立以高效液相色谱法测定注射用卡络磺钠含量的方法。方法:色谱柱为C18,流动相为0.12%磷酸二氢铵缓冲液-无水乙醇(925∶75),流速为0.8ml/min,检测波长为363nm,进样量为10μl,柱温为25℃。结果:卡络磺钠检测浓度在0.08865～0.4432mg/ml范围内线性关系良好(r=0.9999,n=5),平均回收率为99.89%(RSD=1.53%,n=9)。结论:本方法简便、快捷、准确、精密度高,可用于注射用卡络磺钠的质量控制。更多还原

【Abstract】 OBJECTIVE:To establish a method for determination of carbazochrome sodium sulfonate for injection.METH_ ODS:C 18 was used as chromatographic column;the mobile phase consisted of0.12%ammonium dihydrogen phosphate buffer solution-absolute alcohol(925∶75)with detection wavelength at363nm and flow rate at0.8ml/min.The sample size was10μl and the column temperature was25℃.RESULTS:Linear relation was achieved when the concentration of carbzochrome sodium sulfonate was within the range of0.08865mg/ml～0.4432mg/ml(r=0.9999,n=5).The mean recovery rate was99.89%(RSD=1.53%,n=9).CONCLUSION:This method is simple,rapid,accurate,precise,and which can be used as the quality control of carbzochrome sodium sulfonate for injection.更多还原
