摘要
依据GB/T11170-2008《不锈钢多元素含量的测定火花放电原子发射光谱法(常规法)》检测方法和JJF1059-1999《测量不确定度评定与表示》的要求,用ARL4460型直读光谱仪对316L不锈钢中钼元素含量进行不确定度分析,发现分析曲线和样品制备对结果影响比较大。不锈钢中钼元素不确定度评定高了我们实验室检测数据的准确度,同时为其它元素的不确定度评定提供了参考依据。
On the basis of GB/T11170-2008 ＂element determination of stainless steel spark discharge atomic emission spectrometric method（routine method）＂ detection method and JJF1059-1999 ＂evaluation and expression of uncertainty in measurement＂, the content of molybdenum in stainless steel 316 L for uncertainty analysis using ARL4460 spectrometer, analysis influence curve and sample preparation the preparation of the relatively large. The uncertainty evaluation of molybdenum in stainless steel has raised the accuracy of laboratory data and provided a reference for the uncertainty evaluation of other elements.
