Embodiment Construction

[0014] The following examples are intended to further illustrate the present invention, rather than limit the present invention.

[0015] The method for determining the menthol content in cigarette paper by headspace gas chromatography comprises the following steps:

[0016] 1) Preparation of internal standard solution, standard stock solution, and standard working solution: Accurately weigh 0.5 g of phenylethyl propionate into a 500 mL volumetric flask, dilute with DMF (N,N-dimethylformamide) to obtain the internal standard solution (1mg / mL internal standard). Weigh 1.0 g of menthol and 0.1 g of phenylethyl propionate into a 100 mL volumetric flask, dilute to volume with DMF to obtain a standard stock solution (10 mg / mL menthol). Pipette an appropriate amount of standard stock solution and dilute it with internal standard solution to form standard working solutions of 0.1, 0.25, 0.50, 1.0, 2.0, 5.0 mg / mL.

[0017] 2) Sample pretreatment: randomly select three packs from the...

Abstract

The invention discloses a method for measuring the content of piperitol in tobacco paper through headspace gas chromatography. The method comprises the following steps: (1), preparing an internal standard solution, a standard stock solution and a standard work solution; (2), carrying out sample pretreatment: after a cigarette sample is peeled out of a pipe tobacco and an acetate filter tip, a paper sample is directly weighted and placed into a 20 mL headspace bottle, the internal standard solution is added and sample feeding is performed after sealing to a gland; (3), sample measuring: an Agilent headspace gaschromatograph is adopted; (4), carrying out qualitative diagnosis and quantification: standard substance retention time and single standard sample introduction qualitative diagnosis are used for chromatograms of a blank solution, a standard solution and a paper solution; an internal standard method is adopted for quantification, the area ratio y and the concentration ratio x of piperitol and an internal standard peak are used for drawing working curves, so as to obtain corresponding retention time, linear equation, detection limit and determination limit. According to the method, headspace sample introduction is adopted, and the sample pretreatment is simple and easy for automation. The method has the advantages of simplicity, accuracy, automation, wide application range and the like.

Description

technical field [0001] The invention relates to the field of cigarette detection, in particular to an analysis method for determining the menthol content in cigarette paper by headspace gas chromatography. Background technique [0002] Menthol cigarettes are very popular in the global market, and some regions even account for more than 25% of all cigarettes sold. Menthol-type paper (cigarette wrapping paper and cigarette paper, tipping paper, etc.) is one of the important methods for producing menthol-type cigarettes. During production and storage, due to its strong volatility, menthol is easy to re-migrate between shredded tobacco, filter tip and paper (cigarette paper and tipping paper, etc.), and even penetrate into the outer packaging, which increases the analysis time of menthol. sample size and difficulty of analysis. Monitoring the mint content of mint-type paper and cigarette paper during storage is not only helpful for the development of new mint-type paper materi...
