卷烟主流烟气中NNK测量不确定度评定
Uncertainty Evaluation of the Determination of Tobacco Specific NNK in Mainstream Smoke
【摘要】 对气相色谱-热能分析联用法测定卷烟主流烟气总粒相物中NNK含量的测量不确定度进行评定,分析了NNK含量检测的影响因素,计算了不确定度分量及合成不确定度,当NNK含量测定结果为27.4 ng/支时,扩展不确定度为2.0 ng/支。
【Abstract】 The uncertainty in the measurement of NNK content in total particulate matter of cigarette mainstream smoke by GC–TEA method was evaluated.The influence factors on the determination of NNK content were analyzed.The components of uncertainty and combined uncertainty were calculated.The expanded uncertainty was 2.00 ng/cig,as the NNK content was 27.4 ng/cig.
