原子荧光法测定奶粉中砷含量不确定度评定

用测量不确定度表示检测结果是当前国际上约定做法,然而如何对测量结果的不确定度进行合理评定,一直是困扰检测实验室的一个难题。作者依据测量不确定度的评定原则,通过实例,简要地阐述了原子荧光法测定奶粉中砷的不确定度评定方法,对检测领域测量不确定度的评定具有借鉴意义。

Evaluating Study on Measuring Uncertainty of arsenic determination in milk powder with Atomic fluorescence

The uncertainty of measurement to indicate the results of examination is a regular method in the world now. However, how to reasonably evaluate the uncertainty degree of measuring results remains a difficulty problem for the examination laboratory .Based on the rules of uncertainty evaluation in measurement, the article summarized the ways to evaluate the uncertainty in measurement with Atomic fluorescence. This work is of great significance in evaluating the uncertainty degree in the mental monitoring.
