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。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.

关 键 词：气相色谱 热能分析联用法 卷烟 NNK 测量不确定度
