摘要
目的评估采样和检测过程各操作步骤对测定结果的影响。方法先根据测定方法建立不确定度的数学模型,然后逐一对不确定度的分量进行计算。结果相对标准不确定度ur(Bs)=0.030、ur(A-A0)=0.016、ur(V0)=0.029、ur(VL)=0.010,合成相对标准不确定度urc(C)=0.046。结论本法的不确定度主要来源于采样流量、标准溶液的配制和色谱检测的峰面积。
Purpose： Evaluating the sample and test procedure for the test result. Method： Mathematical mode is built according to the test method firstly, and uncertainty components are calculated one by one. Results： relative standard uncertainty are ur（Bs）=0.030, ur（A -A 0）= 0.016,ur（V0）=0.029,ur（VL）=0.010, and combines standard uncertainty is urc（C）=0.046. Conclusion： Uncertainty of this method are mainly from the sample flow, standard solution and test peak area.
