采用二阶导数光谱法测定安定注射液的含量,在紫外分光光度计上用代数校正法消除分解产物、中间体及附加成分的干扰,样品可不经分离直接测定含量。安定的相对平均回收率为100.3%,cv 为0.6%.
Second-order derivative spectrophotometry was used to determine the content of Anding Injection. The aldehyde calibration method was used to eliminate the interference of the decomposition products, intermediates and additional components on the UV spectrophotometer. The content of the sample can be directly determined without separation. The relative average recovery of diazepam was 100.3% and cv was 0.6%.
