连续流动法测定烟草中总糖、还原糖、氯、钾含量的不确定度评定
Uncertainty evaluation of the determination of total sugar, reducing sugar,chlorine,potassium in tobacco
摘要
Abstract
The uncertainty in the measurement for determination of the total sugar,reducing sugar,chlorine,potassium in tobacco by the continuous flow method was evaluated with the actual instance. The influence factors on the uncertainty in the measurement for de-termination of total sugar,reducing sugar,chlorine,potassium con-tent were analyzed,the component and combined uncertainties were calculated,and the expanded uncertainties of the above three compo-nents were 0.44%,0.40%,0.02% and 0.06%,respectively,which providing the credibility and confidence interval to the measurement results.关键词
