Abstract

The invention provides a linear type smoking machine collecting device with an adsorption tube and an analytical test method of the collecting device. The linear type smoking machine collecting device with the adsorption tube comprises the adsorption tube (1), an artificial lip gripper (2), artificial lips (3), a collector front cover (5), a collector rear cover (7) and an adsorption tube holding member (8), wherein the artificial lips (3) are arranged inside the artificial lip gripper (2). According to the device, the operation is simple and convenient, the repeatability of assaying is good, the consumption of an organic solvent is low, the sample test result is free from significant difference from the sample test results of the standard methods, and the collection of volatile organic compounds can be realized at room temperature, so that the device is applicable to the analysis of large-batch samples.

Description

technical field [0001] The invention relates to the technical field of analysis and detection of cigarette smoke, in particular to a collection device of a linear smoking machine with an adsorption tube and a method for analyzing and testing cigarette smoke using the collection device. Background technique [0002] With the in-depth research on smoking and health, people are paying more and more attention to the harmful components in cigarette smoke. Cigarette mainstream smoke contains a large number of volatile organic compounds. Among the 44 harmful components listed on the Health Canada Concerned Detection List, there are 5 volatile organic compounds: 1,3-butadiene, isoprene, acrylonitrile, benzene and toluene. The carcinogenicity of 1,3-butadiene and isoprene is listed by IARC as a possible human carcinogen (2B); benzene is a human carcinogen, and its carcinogenicity is "sufficient data from animal experiments and human experiments" (Group1); IARC lists acrylonitrile a...
