Embodiment 1

[0042] In this embodiment, the detection method for the quantitative analysis of three main trace alkaloids, such as mysamine, anatabine, and anatabine, in mainstream puff-by-puff smoke of slim cigarettes is as follows (the flow chart of the detection method is as follows: figure 1 shown):

[0043] (1) Preparation of internal standard solution

[0044] Accurately weigh 0.2020g of n-heptadecane, dissolve it in methanol in a 100mL volumetric flask and adjust the volume to the mark to obtain an internal standard solution with a concentration of 2020μg / mL.

[0045] (2) Preparation of standard working solution

[0046] ①Single-standard stock solution: Accurately weigh 10.24mg of myosmin, 10.05mg of anatabine, and 5.01mg of anatabine standard samples, transfer each to a 50mL volumetric flask, dissolve in methanol and adjust the volume to the mark to obtain Single standard solutions with concentrations of 204.8 μg / mL, 201 μg / mL and 100.2 μg / mL, respectively.

[0047] ②Mixed standa...

Embodiment 2

[0074] The present embodiment is as follows to the detection method of the precision of the present invention and the standard addition recovery rate:

[0075] Taking the slim cigarette sample used in Example 1 as the sample, the intraday precision experiment was carried out respectively for the smoke of the third cigarette in the third puff. The intraday precision experiment was that the same sample was measured in parallel 6 times under the same conditions (the same batch The relative standard deviation (RSD) of 6 parallel determination results was calculated respectively, and 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.

[0076]

[0077] Taking the slim cigarette sample used in the repeatability test as the analysis object, the smoke of the third cigar...

Abstract

The invention discloses a method for quantitatively analyzing major trace alkaloids in main stream puff-by-puff smoke gas of a fine cigarette. The method comprises the following steps of (1) preparing an inner standard solution; (2) preparing a standard work solution; (3) preparing a sample solution; (4) performing gas chromatography-tandom mass spectrometer analysis; (5) drawing a standard work curve and calculating a sample result. The method has the following beneficial effects that (1) in the method, a gas chromatography-tandom mass spectrometer is creatively used for testing the three kinds of major trace alkaloids of myosmine, neonicotine, anatabine and the like in the main stream puff-by-puff smoke gas of the fine cigarette; the problems of low compound level in the puff-by-puff smoke gas of the fine cigarette and the influence of factors of serious analysis interference of smoke gas complicated substrates in target objects are solved; (2) the method creatively uses a pulse splitless analysis mode by aiming at the characteristics of low target object content in the puff-by-puff smoke gas of the fine cigarette; the response sensitivity of a target object is greatly improved.

Description

technical field [0001] The invention discloses a method for quantitatively analyzing main trace alkaloids in mainstream puff-by-puff smoke of slim cigarettes, and specifically relates to a method for determining main trace alkaloids in mainstream puff-by-puff smoke of slim cigarettes based on gas chromatography-tandem mass spectrometer The alkaloid method belongs to the technical field of cigarette physical and chemical index detection. Background technique [0002] In recent years, with the continuous improvement of people's health awareness, consumers' choice of cigarette products has gradually shifted to high-quality and low-hazard products. The low-tar characteristics of slim cigarettes cater to this trend, making them gradually recognized by consumers. and favored. As a fast-growing new category of Chinese-style cigarettes, slim cigarettes have natural advantages in the fields of harm reduction, coke reduction, cost reduction and efficiency enhancement. However, it is...
