AI Technical Summary

Technical Problem

Existing methods for analyzing cigarette smoke involve numerous steps, consume large amounts of reagents, produce unstable results, and employ complex collection devices that are difficult to control in terms of smoke volume flow rate, leading to the volatilization and escape of volatile compounds and hindering efficient integration with subsequent analyses.

Method used

Smoke gas was captured using a water displacement method, and the smoke from a single cigarette was detected and analyzed by solid-phase microextraction and gas chromatography-mass spectrometry. The smoke gas flow rate was adjusted by controlling the water volume and knob, and ethyl phenylacetate was used as an internal standard to optimize the extraction conditions.

Benefits of technology

It simplifies the flue gas collection process, improves collection and extraction efficiency, enhances the accuracy and consistency of analysis, optimizes analytical conditions, and improves the detection effect of flue gas components.

Abstract

This invention provides a method for analyzing single cigarette smoke, comprising the following steps: 1) collecting single cigarette smoke; 2) extracting smoke to obtain a sample of smoke to be tested; 3) detecting smoke components: inputting the sample of smoke to be tested into a gas chromatograph and performing analysis by gas chromatography-mass spectrometry. This invention belongs to the field of tobacco analysis technology and provides a method for analyzing single cigarette smoke. First, a simple and convenient water-flushing smoke collection device is used to collect cigarette smoke. The inlet of this device can be used to draw in cigarette smoke, and the amount of water collected is controlled. A knob at the outlet prevents smoke loss, which is beneficial for collecting complete single cigarette smoke. The device has a simple structure, high collection efficiency, greater selectivity, and improved accuracy.
