| 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. |
