Method for measuring main carbonyl compounds in main stream cigarette smoke

Abstract

The invention discloses a method for measuring main carbonyl compounds in main stream cigarette smoke, which comprises the following steps of: gathering the main carbonyl compounds in the main stream cigarette smoke with solution, detecting the main carbonyl compounds with a high performance liquid chromatograph in combination with an ultraviolet detector, and quantitatively analyzing the main carbonyl compounds in the main stream cigarette smoke by adopting an external reference method. As the main carbonyl compounds in the main stream cigarette smoke is gathered with the solution, the measurement method provided by the invention has the advantages of greatly improving detection efficiency, simultaneously reducing the loss of an organic solvent, reducing pollution to the environment and fast, efficiently and accurately measuring the content of the main carbonyl compounds in the main stream cigarette smoke, along with simple and convenient operation, high accuracy and sensitivity, high repeatability, and short detection time, namely, a detection period only comprises about 35 minutes.

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 measuring main carbonyl compounds in cigarette mainstream smoke. Background technique [0002] Carbonyl compounds in cigarette mainstream smoke are an important class of harmful components in cigarette mainstream smoke, and have been included in the list of 46 harmful components of the Canadian government and the list of control components recommended by the WHO "Tobacco Product Regulation Research Group". Therefore, it is accurate Determining the content of main carbonyl compounds in cigarette mainstream smoke is of great significance for evaluating the harmfulness of cigarettes. At present, the detection of main carbonyl compounds in cigarette mainstream smoke generally adopts the high performance liquid chromatography method stipulated in "YC / T254-2008". It is processed by adding derivatization reagents, and it ...

AI Technical Summary

Problems solved by technology

At present, the detection of main carbonyl compounds in cigarette mainstream smoke generally adopts the high performance liquid chromatography method stipulated in "YC / T254-2008". It is processed by adding derivatization reagents, and needs to be left overnight in a vacuum drying oven, which takes a long time, so it is easy to cause the loss of target compounds during batch sample analysis, affecting the accuracy of test results, and the detection efficiency is low

At the same time, the longer detection period also increases the consumption of organic solvents, causing environmental pollution
