Problems solved by technology

However, this filter trapping method needs to put two Cambridge filter discs in the trap, and the existing trap design is based on one filter disc, and the superposition of two filter discs will make the capture The problem of poor sealing of the collector
At the same time, the derivatizer prepared with acetonitrile will stick to the trap and be difficult to clean, not only causing inaccurate analyte residue results but also making the trap dirty and difficult to clean

Abstract

The invention provides a turntable type smoking machine collecting device with an inner chamber. The smoking machine collecting device comprises an adsorption block (1), a collector upper cover (2), a collector lower cover (3), a collector lower cover inner chamber (4) and a collector lower cover circular disc (5), wherein the hollow lower cover inner chamber (4) is formed inside the collector lower cover (3), and the adsorption block (1) is located in the lower 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 volatile organic compounds and carbonyl compounds can be realized simultaneously 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 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 amount of volatile organic compounds and carbonyl compounds. Among the 44 harmful components listed in the Health Canada Concerned Testing List, there are 5 kinds of volatile organic compounds: 1,3-butadiene, isoprene There are 8 kinds of carbonyl compounds: formaldehyde, acetaldehyde, propionaldehyde, acetone, acrolein, crotonaldehyde, 2-butanone, butyraldehyde. Therefore, the effective capture and accurate determination of volatile organic compounds and carbonyl compounds in cigarette...
