The disadvantage of this method is that the analysis and determination time is long, and a detection cycle takes about 40 minutes. During the batch sample analysis process, it is easy to cause the oxidation loss of the test sample, which affects the accuracy of the test results. At the same time, the long detection cycle also makes the organic Increased solvent consumption, causing environmental pollution

Abstract
The invention discloses a method for determining main phenolic compounds in main stream smoke of a cigarette. The method comprises the following steps of: gathering the main phenolic compounds in the main stream smoke of the cigarette by using a glass fiber filter disc; and performing on the main phenolic compounds in the main stream smoke of the cigarette by using an ultrahigh-efficiency liquid chromatograph and a fluorescence detector by an external standard method. The determining method provided by the invention has the advantages of short detection time (only about five minutes for one detection period), high sensitivity and high repeatability. Due to the adoption of the method for detecting main phenolic compounds, the content of the main phenolic compounds in the main stream smoke of the cigarette can be rapidly, high-efficiently and accurately detected.
Description
technical field [0001] The invention relates to the technical field of physical and chemical testing of cigarette mainstream smoke, in particular to a method for determining main phenolic compounds in cigarette mainstream smoke. Background technique [0002] The phenolic compounds in the mainstream smoke of cigarettes are an important class of harmful compounds in the mainstream smoke of cigarettes, which have been included in the list of 46 harmful components of the Canadian government and the control recommended by the World Health Organization "Tobacco Product Regulation Research Group" ingredient list. Therefore, accurate determination of the content of main phenolic compounds in mainstream smoke of cigarettes is of great significance for evaluating the harmfulness of cigarettes. At present, the detection of main phenolic compounds in mainstream smoke of cigarettes generally adopts the high liquid chromatography. The disadvantage of this method is that the analysis and...
