清洁验证的回收率应该是包括取样方法的回收率和分析方法的回收率,而不仅仅是sampling recovery。
PDA TR29中有定义为:
recovery study: a laboratory study combining the sampling method and analytical method to determine the quantitative recovery of a specific residue for a defined surface.
for swab abd rinse sampling, recovery studies may be performed as a part of the analytical method validation or they may be performed as separate studies once it is determined that the analytical method can appropriately measure residues in solutions.
就是说一般的很多企业是将分析方法的回收率和取样回收率一起做了,就是叫做总回收率。但是选择测总回收率好呢,还是选择测定单个回收率好呢???(这个是不是和相应的供试品浓度以及其检测方法的定量限有关???)
但是下文有一个关于回收率取舍计算(90%,50%)的问题,那么这个回收率是指总回收率还是取样回收率呢????@hongwei2000 @windy
