ceftriaxone sodium%determination
目的:建立注射用头孢曲松钠中头孢曲松的含量测定方法。方法:HPLC 法;C18柱(4.6×150mm,5μm);流动相:0.02mol/l正辛胺溶液-乙腈(73∶27);流速:1.0 ml/min;检测波长:254nm;柱温:20℃;进样量:20μl。结果:头孢曲松在浓度91.9~459.6μg/ml与峰面积有良好的线性关系(r=0.9996)。结论:该法简单,专属性强,准确度高,可用于对注射用头孢曲松钠的质量控制。
目的:建立註射用頭孢麯鬆鈉中頭孢麯鬆的含量測定方法。方法:HPLC 法;C18柱(4.6×150mm,5μm);流動相:0.02mol/l正辛胺溶液-乙腈(73∶27);流速:1.0 ml/min;檢測波長:254nm;柱溫:20℃;進樣量:20μl。結果:頭孢麯鬆在濃度91.9~459.6μg/ml與峰麵積有良好的線性關繫(r=0.9996)。結論:該法簡單,專屬性彊,準確度高,可用于對註射用頭孢麯鬆鈉的質量控製。
목적:건립주사용두포곡송납중두포곡송적함량측정방법。방법:HPLC 법;C18주(4.6×150mm,5μm);류동상:0.02mol/l정신알용액-을정(73∶27);류속:1.0 ml/min;검측파장:254nm;주온:20℃;진양량:20μl。결과:두포곡송재농도91.9~459.6μg/ml여봉면적유량호적선성관계(r=0.9996)。결론:해법간단,전속성강,준학도고,가용우대주사용두포곡송납적질량공제。
To estabilish a method for the determination of ceftriaxone sodium for injection.MethodHPLC C18 (4.6 ×150mm, 5μm)column was used with n-octylamine (0.02mol/l)and acetonitrile (73:27).The flow rate was 1.0 ml/min.The detec-tion wave length was 254nm.The column temperature was at 20℃,and the inject volume was 20μl.Results The linearities of cefazo-lin sodium were obtained separately over the rang of were 91.9μg/ml~459.6μg/ml (r=0.9996).Conclusion This Method is simple,accurate,and could be adopted for the quality control of this durg .
