Determination of Volatile Organic Acids in Tobacco and Products
Determination of Volatile Organic Acids in Tobacco and Products Details:

Name: Capillary Column
Stationary phase: nitroterephthalic acid modified polyethylene glycol
Specification: 30m*0.25mm*0.25um
Model: HH-FFAP
Application: YC/T 500-2014 Tobacco and tobacco products Determination of volatile organic acids Gas chromatography-mass spectrometry

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. reviewed the latest developments in the field of chemical analysis of tobacco components and the application of some new analytical methods. On the basis of previous research work, new research and discussion were carried out, and the systematic analysis method and identification technology of chemical composition of tobacco and its products were proposed. Mainly did the following exploratory work: Put forward a new idea to grasp tobacco quality in general, not only focus on the content of certain components in tobacco, but on this basis, explore the effects of multiple components on tobacco quality at the same time effect. The content of cell wall substances in tobacco was analyzed and determined, and the correlation between its content and tobacco quality was discussed. At the same time, the content of total volatile organic acid in tobacco and the total acidity of tobacco water leaching were determined, and the content of certain important components in non-volatile organic acid was determined by gas chromatography. A series of organic solutions of different polarities were used to extract tobacco. According to the principle of similar compatibility, the effects of the substances extracted from different organic solutions on the quality of tobacco were preliminarily discussed in terms of total amount. The sterols in tobacco were analyzed and the main ingredient β-sitosterol was determined. The polyphenols in tobacco were separated and analyzed to determine the content of chlorogenic acid. The chlorine and potassium elements that affect the combustibility of tobacco were analyzed and determined, and the changes of Cl/K in different qualities of tobacco were discussed.
