PA (Pro analysis 分析用)---GR (Guaranteed reagent 优级纯);
Puriss (Purissmum 特纯)---grade below GR 低于优级纯
Pur (Pure purum 纯)---CP (Chemical pure 化学纯)
从上面看应该是不太对应的。
katherinew 发表:有个国外的工程师给了一个这样的对应关系。对吗?
p a (pro analysis)--G.R.(guaranteed reagent)
puriss(purissmum)---General purpose reagent (grade below GR
purum(pure purum) --extrapure C.P.(chemically pure)- lowest quality
