摘  要:
本文应用误差理论,遵照JJF1059-1999规范对AFS-2201原子荧光光度计汞检出限的测量不确定度的来源进行了分析,通过实验所得数据,计算合成标准不确定度及有效自由度、扩展不确定度,并对仪器性能做出了评定,提出此台仪器已不适合于低含汞量样品的分析。

摘  要:
The source of the measurement uncertainty on Hg of detection limit in AFS-2201 atomic fluorescence spectrometer is analysed according to error theory and JJF1059-1999 regulation.Based on the experiment data,the combined standard uncertainty,the effective degrees of freedom,and the expanded uncertainty are calaulated,morever,the performance of the AFS2201 is evaluated and put forward the suggestion that this instrument AFS-2201 is not proper for the analysis of samples containing micro Hg.
