[0022] 1. Sample collection and initial treatment.
[0023] Three different authentic cigarettes were collected according to the cigarette sampling standard (GB / T 5606.1-2004), and at least ten production batches of each cigarette were used as modeling samples. The collected cigarettes were disassembled, the wrappers were removed, and placed at 22° C. and 60% relative humidity to equilibrate for at least 48 hours. The balanced shredded tobacco was put into a pulverizer for pulverization, passed through a 40-mesh sieve, and about 30 g of each sample was collected. Put the pulverized samples into double-layer ziplock plastic bags and store them in a refrigerator at 4°C. A 1g sample of tobacco dust was taken from each modeling sample and mixed as a quality control sample (QC sample). Assign a random number to all model group samples. Sample processing and instrumental analysis were performed in random numbered order. This allows for the subtraction of systematic errors introd...
