F.2.13 Working solutions (Calibrating Standards).
Sequentially dilute diluted stock solution (M2) with mobile phase (F.2.14), after addition of 2,5 ml ammonia
(F.2.5.1) and 2,5 ml hydrochloric acid (F.2.8), in order to obtain standards to be used for calibration according
to the scheme in Table F.1. Allow the working solutions to stand for 1 h at 50 °C.
是有加氨水和盐酸这个操作的，是为了跟样品的基体匹配。娴闲(v2665123) 发表:是加氨水中和吧？哪里有加盐酸啊？ICPMS版那边有讨论，貌似标样都能做得很低，但基体干扰和实际样品回收率是个问题。

看得真仔细啊。
这样就可以消除基体干扰码？有没有版友做过的。jiangshilei1984(jiangshilei1984) 发表:F.2.13 Working solutions (Calibrating Standards).
