Embodiment 1

[0029] Select brand A cigarettes, perform sample balance according to the conditions specified in the GB / T 16447 standard, and select (average mass ± 0.02) g and (average draw resistance ± 50) Pa cigarettes for sample testing. Install the prepared trap on the smoking machine, and carry out suction under the conditions specified in the ISO standard, with a suction volume of 35 mL, a suction time of 2 s, a suction frequency of 60 s, and one cigarette per time. After the cigarette smoking and trapping is completed, the trap is removed, and the adsorption material and the front and rear sieve plates are transferred to the corresponding container for extraction treatment. Make a blank sample in the same process, and compare the processing results of the blank sample with the processing results of A cigarette.

[0033] Select brand B cigarettes, perform sample balance according to the conditions specified in the GB / T 16447 standard, and select (average mass ± 0.02) g and (average draw resistance ± 50) Pa cigarettes for sample testing. Install the prepared trap on the smoking machine, and smoke under the conditions specified in the Canadian Intensive Inhalation (HCI) standard, with a suction volume of 55 mL, a suction time of 2 s, a suction frequency of 30 s, and one cigarette per time. After the cigarette smoking and trapping is completed, the trap is removed, and the adsorption material and the front and rear sieve plates are transferred to the corresponding container for extraction treatment. Make a blank sample in the same process, and compare the processing results of the blank sample with the processing results of B cigarettes.

Abstract

The invention provides a linear smoking machine trapping device with an inner cavity and an analysis and testing method thereof, comprising an adsorption block (1), an artificial lip holder (2), an artificial lip (3), a gasket (4), Trap front cover (5), Cambridge filter (6), trap back cover (7) and trap back cover cavity (8), artificial lip (2) in artificial lip holder (2) Inside, the front end of the trap front cover (5) is connected to the artificial lip holder (2), and the rear end is connected to the trap rear cover (7), and the trap rear cover (7) is provided with a hollow rear cover inner cavity (8 ), the adsorption block (1) is located in the inner cavity of the back cover (8), the device is easy to operate, has good measurement repeatability, less consumption of organic solvent, no significant difference between the sample test results and the standard method, and can be achieved at room temperature The capture of volatile organic compounds is suitable for the analysis of large batches of samples.

Description

technical field [0001] The invention relates to the technical field of cigarette smoke analysis and detection, in particular to a linear smoking machine trapping device with an inner cavity and a method for analyzing and testing cigarette smoke using the trapping 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 as a carcinogen ...
