替硝唑注射液尚未载入中国药典,其含量测定方法亦不统一,有的单位已采用吸收系数法,但吸收系数也不统一。为确定一个准确的替硝唑吸收系数,以供药典收载参考,特做如下实验。 1 主要仪器与试剂 紫外分光光度计:7520;751—G;UV—730(上海分析仪器厂);UV—160A;UV—260(日本岛津)。替硝唑标准品(含量99.5％,批号:78362,印度CHEMPHAR),自制替硝唑注
Tinidazole injection has not yet been included in the Chinese Pharmacopoeia, its content determination method is not uniform, and some units have adopted the absorption coefficient method, but the absorption coefficient is not uniform. In order to determine an accurate tinidazole absorption coefficient, for the Pharmacopoeia reference, special make the following experiment. 1 main instruments and reagents UV spectrophotometer: 7520; 751-G; UV-730 (Shanghai Analytical Instrument Factory); UV-160A; UV-260 (Shimadzu). Tinidazole standard (content 99.5%, batch number: 78362, India CHEMPHAR), homemade tinidazole Note
