摘要
为确保检测数据的准确性和可靠性,有必要对测定方法进行不确定度评定。根据测量不确定度评定方法,分析了离子色谱仪测量电厂水汽系统蒸汽钠离子的主要不确定度来源,明确了各不确定度分量的大小。评定结果表明:离子色谱仪测量电厂水汽系统蒸汽钠离子不确定度的主要来源由标准工作曲线拟合产生,而测量重复性、加标回收率及标准工作溶液的配制也是引入不确定度的因素。
In order to ensure the accuracy and reliability of the test data, it is necessary to evaluate the uncertainty of ion chromatography. Using the uncertainty evaluation methods, this paper analyzes and quantifies the main uncertainty sources of trace sodium in the power plant water and steam system measured by ion chromatography. The outcome of the uncertainty evaluation indicates that the uncertainty in the trace sodium measurement mainly results from the standard curve fitting. Other affecting factors include the repeatability, recovery and preparation of the standard solution.
