连续流动法测定烤烟型卷烟烟丝中氯含量不确定度评定

Determination of Uncertainty of Chloride in Tobacco of Virginian-type Cigarette by Continuous Flow Method

摘要: 连续流动法是烟草及烟草制品中中氯含量最常用的分析方法. 以氯化物为实例, 进行了连续流动法测定烤烟型卷烟烟丝中氯含量的不确定度评定,得出连续流动法烤烟型卷烟氯测量结果的标准不确定度为0.03%,在95%的置信度下,取包含因子k为2,其扩展不确定度为0.06%.

Abstract: The continuous flow method is the most popular method to determine the concentration of chloride in tobacco and tobacco products. In the case of chloride, the uncertainty of chloride in virginian-type cigarette was evaluated. The standard uncertainty was 0.03%, the extend uncertainty (α=0.05, k=2) was 0.06%.
