Embodiment 1
[0032] A method using IMR-MS to quickly evaluate the quality stability of cigarette mainstream smoke online, using a rotary smoking machine to obtain cigarette mainstream smoke, and making the smoke directly quantitatively enter IMR-MS, and quickly obtain cigarette mainstream smoke through IMR-MS The response value (cps) of each volatile compound ion in the air, drawing the mass spectrum fingerprint of cigarette mainstream smoke, combined with similarity analysis, and comparing the qualified threshold of mainstream smoke quality stability, to realize the rapid evaluation of cigarette mainstream smoke quality stability .
[0033] Specifically include the following steps:
[0034] S1, sample preparation;
[0035] Prepare 10 batches of qualified Yunyan (soft treasure) cigarettes produced in March-June 2016, and select 5 cigarettes with an average weight ± 0.01g and an average draw resistance ± 49Pa for each batch of cigarettes as control cigarettes; in addition, prepare 2 batche...
Embodiment 2
[0054] In order to investigate the applicability of the present invention to other cigarette brands, embodiment 2 is implemented according to embodiment 1, and corresponding adjustments are made in the following aspects:
[0055] In Example 2, prepare 10 batches of qualified Yuxi (hard and harmonious) cigarettes produced in March-July, 2016, and select 5 cigarettes with an average weight ± 0.01g and an average draw resistance ± 49Pa for each batch of cigarettes as a control cigarette; In addition, one batch of Yuxi (hard harmony) cigarettes produced in August 2016 (batch 1) and August 2015 (batch 2) were prepared as the cigarettes to be tested. Each batch selected 5 cigarettes according to the above method for the experiment. The implementation mode is carried out according to Example 1, and the average mass spectrum fingerprint of qualified Yuxi (hard and harmonious) cigarettes is as follows: figure 2 shown. Table 3 shows the calculation results of the similarity between th...
