应用误差叠加原理评价色谱内标法
Estimation of the Internal Standard Technique in Chromatography Using Law of Propagation of Error
-
摘要: 本文应用误差叠加原理,对药物分析中的内标定量法进行了评价。五个实际例子说明,内标法改善分析方法精密度的条件是CV;s<2rCV,i。作者提出了在药物分析中所用内标法的条件。本文表明内标法除了其优点外,还存在一些局限性。Abstract: It is possible to estimate how the internal standard technique affects the precision of a chr-omatographic method in pharmaceutical analysis by use of the law of propagation of error. Theuse of this method is demonstrated with 5 practical examples. Condit
