Method for testing relation between cigarette paper pore structure and CO release in main stream smoke in cigarette burning process

[0030] 1) Take A, B, and C three groups of 1# cigarette paper samples of the same type, and A cigarette paper includes A of the same type 1 and A 2 Cigarette paper, B cigarette paper including B 1 and B 2 cigarette paper;

[0031] Accurately weigh the mass of each cigarette paper sample: put the cigarette paper to be tested into a pre-weighed nitrogen adsorption-desorption sample tube, and pre-dry at 80°C for about 5 hours under nitrogen purge until all the water vapor is absorbed. Take it away, the quality of the cigarette paper will not change, put the dried sample tube in the cooling tank to cool to room temperature, weigh the quality of the sample tube again, and obtain the cigarette paper A 1 with B 1 The masses are 0.2228g and 0.2045g respectively, and put into the blank sample tube as a reference at the same time;

[0032] 2) will be fitted with a 1 Put the sample tube of cigarette paper into the nitrogen adsorption and desorption instrument, and put the A measure...
