手持式X荧光分析仪分析不锈钢中Cr、Ni、Mn的不确定度评定

Uncertainty Evaluation of Cr,Ni and Mn in Stainless Steel by Handheld X-ray Fluorescence Analyzer

用手持式X荧光分析仪对不锈钢中Cr、Ni、Mn元素进行测定,分析了不锈钢中Cr、Ni、Mn元素的不确定度来源,并对不确定度因素进行评定,计算出了用手持式X荧光分析仪测定不锈钢中Cr、Ni、Mn元素的各不确定度分量、合成标准不确定度和扩展不确定度。本文的分析数据为手持式X荧光分析仪的检测分析提供了可靠的数据支撑,为我公司采用X荧光分析仪分析合金材质提供了依据。

The content of Cr,Ni and Mn in stainless steel was tested by handheld X-ray fluorescence analyzer. The uncertainty sources of Cr,Ni and Mn in stainless steel were analyzed and the uncertainty factors were evaluated. The components of standard uncertainty,combined standard uncertainty and expanded uncertainty were calculated by handheld X-ray fluorescence analyzer. These data would provide references for analyzing measure results by handheld X-ray fluorescence analyzer.
