Problems solved by technology

Solution absorption requires additional connection of pipelines, and the operation is cumbersome; when using Cambridge filters to capture carbonyl compounds in cigarette smoke, two filters are required for effective capture, and Cambridge filters also need to be derivatized. Reagents are easy to stick to the trap and difficult to clean, resulting in inaccurate analyte residue results and difficulty in cleaning the trap. At the same time, the trap will not be tightly sealed due to the use of two Cambridge filters

Embodiment 1

[0025] Select brand A cigarettes, perform sample balance according to the conditions specified in the GB / T 16447 standard, and select cigarettes with an average mass of ±0.02g and an average draw resistance of ±50Pa 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 35.0 mL, a suction time of 2 s, and a suction frequency of 60 s. Aspirate one tube at a time; remove the trap after trapping, transfer the adsorbent material and the front and rear sieve plates to the corresponding container for extraction treatment; make a blank sample in the same process.

Abstract

The invention provides a linear smoking machine trapping device with an inner cavity, comprising an adsorption block (1), an artificial lip holder (2), an artificial lip (3), a gasket (4), and a front cover of the trap (5), Cambridge filter (6), trap back cover (7) and trap front cover cavity (8), artificial lip (3) is located inside the artificial lip holder (2), trap The front end of the front cover (5) is connected to the artificial lip holder (2), and the rear end is connected to the back cover of the trap (7). The front cover (5) of the trap is provided with a hollow front cover inner cavity (8), and the adsorption block ( 1) Located in the inner cavity (8) of the front cover, the device is easy to operate, has good measurement repeatability, consumes less organic solvent, and has no significant difference between the sample test results and the standard method, and 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. Carbonyl compounds are a class of harmful substances in mainstream cigarette smoke. There are 8 substances in total: formaldehyde, acetaldehyde, propionaldehyde, acetone, acrolein, crotonaldehyde, 2-butanone, and butyraldehyde. Carbonyl compounds are one of the 44 harmful components listed by Health Canada. Therefore, the effective capture and accurate determination of carbonyl compounds in cigarette smoke has practical significance for smoking and health research. At present, there are two main methods for the collection of carbonyl compound...
