摘要
分析了离子色谱法测定水样中氯离子不确定度的来源,包括标准系列配制引入的不确定度、标准系列浓度-峰面积拟合直线引入的不确定度、样品稀释引入的不确定度,计算了不确定度分量及合成不确定度,扩展不确定度为5.6%。
The sources of uncertainty of measurement for determination of chloride ion in water by ion chromatography were analyzed, which included the standard solution preparing, standard solution concentration - peak area fitting curve and diluting solution. The uncertainty components were calculated and combined, the expanded uncertainty was 5.6%.
