Problems solved by technology

[0006] However, so far, no report has been found on the accurate quantitative analysis of the main moss-like aroma substances in the mainstream smoke of slim cigarettes, and there is a lack of quantitative information on the key moss-like aroma substances in the smoke of a single cigarette, which is crucial for the analysis. Relationships between aroma substances and cigarette style characteristics with lagged effects

Embodiment 1

[0038] In this embodiment, the detection method of the trace main moss fragrance characteristic aroma substances in the mainstream smoke of slim cigarettes is as follows (the flow chart of the detection method is as follows:figure 1 shown):

[0039] (1) Preparation of internal standard solution

[0040] ①Internal standard stock solution: Accurately weigh 0.2020g of n-heptadecane, dissolve it in methanol in a 100mL volumetric flask and bring the volume up to the mark.

[0041] ②Internal standard solution: Accurately pipette 0.1mL of internal standard stock solution into a 100mL volumetric flask, dilute with methanol and bring the volume up to the mark. The concentration of n-heptadecane was 2.02 μg / mL.

[0042] (2) Preparation of standard working solution

[0043] ① Primary standard stock solution: Accurately weigh 0.2986g ethyl orcinol monomethyl ether, 0.1169g orcinol monomethyl ether and 0.2499g β-orcinol carboxylate methyl ester, accurate to 0.1mg, into a 50mL volumetric ...

Embodiment 2

[0071] The present embodiment is as follows to the detection method of the precision of the present invention and the standard addition recovery rate:

[0072] Taking the slim cigarette samples used in Example 1 as the analysis object, the intraday precision experiment was carried out respectively. The intraday precision experiment was that the same sample was measured in parallel 6 times under the same conditions (same batch processing), and the 6 parallel tests were calculated respectively. The relative standard deviation (RSD) of the measurement results, the measurement results are shown in the table below. The results in the table show that the intraday repeatability RSD of this experimental method is less than 10%, which indicates that the method has good precision for the quantitative analysis of trace substances.

[0074]

[0075] Take the slim cigarette sample used in the repeatability test as the analysis object, process it according to the above-mentio...

Abstract

The invention provides a quantitative analysis method of main moss fragrance characteristics flavor components in fine cigarette mainstream smoke. The method comprises the following steps of (1), internal standard solution preparation; (2), standard work solution preparation; (3), sample solution preparation; (4), gas chromatography and tandem mass spectrometer analysis; (5), standard work curve drawing and sample result calculation. The quantitative analysis method of the main moss fragrance characteristics flavor components in fine cigarette mainstream smoke has the advantages that according to the quantitative analysis method, three main micro flavor component contents including soft evernia ethyl acetate, Monomethyl phenol monomethyl ether, beta Monomethyl phenol carboxylic acid methyl ester and the like of trace amount in the fine cigarette mainstream smoke are measured by using the gas chromatography and tandem mass spectrometer, and influence by the low content of the compound in the smoke and severe disturbance for the analysis of the objects of the smoke complex matrix is avoided. The quantitative analysis method of the main moss fragrance characteristics flavor components in fine cigarette mainstream smoke is high in sensitivity, high in repeatability and recovery rate, and suitable for the quantitative analysis of the trace amount objects in the fine cigarette smoke complex matrix.

Description

technical field [0001] The invention discloses a method for quantitatively analyzing the main moss and characteristic fragrance substances in the mainstream smoke of slim cigarettes, in particular to a gas chromatography-tandem mass spectrometer-based method for determining the trace amount of main moss in the smoke of slim cigarettes The invention discloses a method for characteristic fragrance substances of light fragrance, which belongs to the technical field of detection of physical and chemical indexes of cigarettes. Background technique [0002] Due to its novel appearance and stylish design, slim cigarettes are particularly favored by consumers who pursue fashion trends, highlight their individuality, and live an elegant life. It was initially accepted by American consumers in the 1980s, and gradually became popular in the European and Korean markets, becoming an important pole in the cigarette market. In recent years, the proportion and status of slim cigarettes in ...
