火焰原子吸收法测定人发中锌含量检验结果测量不确定度评定

Uncertainty evaluation in measurement of human hair by flame AAS

本文通过采用微波前处理方法对人发进行处理后 ,用原子吸收分光光度计测定人发中锌含量的全过程分析 ,尝试找出该检测过程中测量不确定度来源并进行评定 。

Element Zn of human hair had been determined by flame AAS after pre-treatment by micro-wave instrument. During the whole analysis, we tried to find all kinds of uncertain resources to evaluate its uncertainty measurement. This article only affords an example for the labs that want it.
