如何评估回收率测量结果不确定度

How to evaluate measurement uncertainty of recovery ratio

加标回收率方法是测定复杂基体中待测物的重要而普遍适用的方法。然而,人们对回收率测量结果不确定度的评估和它对待测物测量结果不确定度评估中的贡献却关注较少。现就回收率测量结果不确定度评估及如何对待测物测量结果的修正进行讨论。

Recovery method which is important in analytes determination from complex matrices has been widely used.However,it doesn't get enough attention on assessment of the recovery measurement uncertainty and its contributes to impact on the analyte measurement uncertainty evaluation.The recovery uncertainty in measurement evaluation was discussed in this paper to find the right to the measurement result correction.
