Embodiment 1

[0041] 1 material

[0042] 1.1 Instrument

[0043] 6890GC / 5973MS gas chromatography / mass spectrometry (Agilent, USA); TurboMatrix ATD thermal desorption instrument (Perkin Elmer, USA); Carbotrap349 adsorption sampling tube, gas collection pump (Supelco, USA); flow meter (AALBORG, USA) .

[0044] 1.2 Reagents and samples

[0045] Cigarette samples (selected from Shanghai Cigarette Factory); menthol standard samples (purity 99.0%, Bailingwei Technology Co., Ltd.); absolute ethanol (purity 99.9%, American ACS Enke Chemicals).

[0046] 2 methods

[0047] In order to analyze the impact on the surrounding environment during the production of menthol cigarettes, the following experiments were carried out to investigate the diffusion and concentration changes of menthol in the production environment: In the same production site, 1# machine produced menthol cigarettes, 2#, 3#, Machine 4# produces other types of cigarettes at the same time (distance from machine 1#: 2#<3#<4#).

Abstract

The invention provides a method for analyzing influence of a mentholated cigarette processing process on a production environment, aiming at solving the problem in the prior art that the menthol content in a mentholated cigarette production environment can not be accurately measured. According to the invention, an atmosphere sample during the mentholated cigarette processing process is captured through an on-line capturing device, and the concentration of menthol in the mentholated cigarette production environment is measured by a thermal desorption-gas chromatography-mass spectrography technology. The method is simple to operate and reliable to quantify, an analysis result is accurate and effective, the linear relation of a standard curve is good, the correlation index r<2> equals to 0.9999, a detection limit of the method reaches 0.34 microgram / m <3>, the recovery rate of the menthol in the production environment is 97.92% to 102.38%, and the relative standard deviation (RSD) is 6.57%. The method ensures the reliability and objectivity of an environmental menthol quantifying result in the cigarette processing process, and is of great significance to alleviation of pollution to a production line and a production environment.

Description

technical field [0001] The invention relates to a method for analyzing the influence of a menthol cigarette processing process on the production environment, and belongs to the technical field of environmental detection and analysis. Background technique [0002] The production of menthol cigarettes began in the 1920s and 1930s. Since its inception, the output has gradually increased. Currently, menthol cigarettes account for about one-third of the total cigarette sales in the US market alone. Menthol cigarettes referred to herein refer to cigarettes with a certain content of menthol. Tobacco itself does not contain menthol, and the mint flavor in cigarettes is mainly added by spices. By adopting a certain slow-release technology, an appropriate amount of menthol can be added to the cigarette filter rod, which is one of the important production methods of mint cigarettes. Menthol, also known as hexahydrothymol, commonly known as menthol, is an extract in plants, can be isol...
