If there is no Primary Reference Standard available (e.g.
for by-products and degradation products), evidence of identity must be established
independently for each batch of Secondary Reference Standard.
如果没有初级对照品,那么二级对照品每一批次都需要单独确认其?
这里identity是指什么?对照品的各种参数么?
Qualification/comparability studies of Secondary Reference Standards must be performed for any
replacement batch of either the primary or the secondary Reference Standard.
更换初级或者次级对照品的时候,必须对次级对照品进行确认/相似性研究?
二级对照品大多是自己标定的或者来源于非官方的标准物质
evidence of identity must be established independently for each batch of Secondary Reference Standard
原文说的很清楚,每一批二级标准物质都要进行鉴定,鉴定项我认为还是要参考药典。
基本和楼上的看法一样
