ICP发射光谱仪锌元素检出限不确定度分析

Analysis on the Uncertainty of the Limit of Detection of Zinc with ICP Emission Spectrometer

依据JJG1059-1999对ICP发射光谱仪锌元素检出限的不确定度进行了评估,分析了影响测量不确定度的各个因素,计算得出ICP发射光谱仪锌元素检出限的扩展不确定度为:U=0.00066(μg.mL-1),k=2。

Based on JJG1059-1999,the uncertainty of the limit of detection of zinc with ICP Emission Spectrometer was assessed.At the same time,the various elements which effected the uncertainty of measurement were analyzed.The expanded uncertainty was obtained by calculation:U = 0.00066(μg·mL-1),k=2.
