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

Abstract

The invention provides a turntable type smoking machine collecting device with an adsorption tube and an analytical test method of the collecting device. The smoking machine collecting device comprises an adsorption tube (1), a collector upper cover (2), a collector lower cover (3), a collector upper cover inner chamber (4) and a Cambridge filter (5) and is characterized in that the hollow upper cover inner chamber (4) is formed inside the collector upper cover (2), and the adsorption tube (1) is located in the upper cover inner chamber (4). 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 carbonyl 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 rotary disk type smoking machine trapping device with an adsorption tube 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 c...
