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...

Abstract

The invention discloses an online rapid evaluating method for the cigarette main-stream-smoke-quality stability through IMR-MS. The online rapid evaluating method includes the steps that cigarette main-stream smoke is obtained through a rotating-disc-type smoking machine, smoke directly and quantitatively enters the IMR-MS, response values of all volatile compound ions in the cigarette main-stream smoke are rapidly obtained through the IMR-MS, the mass spectrum fingerprint spectrum of the cigarette main-stream smoke is drawn, similarity analysis is combined, a qualified threshold value of the main-stream-smoke-quality stability is compared to achieve rapid evaluation of the cigarette main-stream-smoke-quality stability. The method has the advantages that the method is combined with the cigarette production reality, the IMR-MS is applied to research of the cigarette main-stream-smoke-quality stability, and the online real-time analysis method which is rapid, comprehensive and free of pretreatment is provided for cigarette main-stream-smoke-quality stability evaluation, and a convenient and effective mode is provided for quality-guaranteeing maintenance work of all cigarette brands.

Description

technical field [0001] The invention relates to the technical field of cigarette smoke analysis, in particular to a method for quickly evaluating the quality stability of cigarette mainstream smoke on-line by using IMR-MS (Ion Molecular Reaction Mass Spectrometry). Background technique [0002] Tobacco is a crop that is not eaten directly, and the value of tobacco is mainly reflected by consumers inhaling the burned smoke to meet their needs. This special property of tobacco determines that cigarette smoke has become the most important symbol of cigarette products for consumers, and is the most important factor reflecting the quality level and style characteristics of cigarettes. The smoke quality that consumers can feel also directly affects the smoking quality of cigarettes, thereby determining consumers' purchase intentions for cigarettes. Therefore, each cigarette manufacturer has always been committed to maintaining the stability of the smoke quality of existing cigare...
