Abstract

The present invention discloses a method for concurrently detecting 23 ester compounds in a cigarette water-base adhesive. The method comprises that: standard solutions of various ester compounds are detected through a gas chromatograph-mass spectrometer, and a standard curve is drawn by using an internal standard method; and a cigarette water-base adhesive sample is extracted through liquid-liquid extraction to obtain the solution requiring detection, the solution requiring detection is detected through the gas chromatograph-mass spectrometer, and contents of various ester compounds in the solution requiring detection are calculated according to the standard curve. According to the method, rapid, accurate and concurrent detection of 23 ester compounds in a cigarette water-base adhesive is achieved, and advantages of high sensitivity, good repeatability and the like are provided.

Description

technical field [0001] The invention relates to a method for simultaneously detecting 23 kinds of ester compounds in tobacco water-based glue, belonging to the technical field of tobacco analysis. Background technique [0002] Water-based glue is a viscous mixed emulsion that is neutral or weakly acidic at room temperature with a water-soluble or water-dispersible solvent as the medium. Compared with organic solvent-based adhesives, water-based adhesives have the advantages of no solvent release, non-flammability, safe use, and low cost. They have been widely used in packaging and printing, wood processing, cigarette manufacturing, and papermaking industries. Tobacco water-based glue is the water-based glue used in the cigarette manufacturing process, mainly including water-based glue for cigarettes and water-based glue for packaging. [0003] Affected by production raw materials, polymerization conditions, additives, etc., some harmful compounds remain in water-based adhes...
