Example Embodiment

[0024] Specific implementation method

[0025] In order to further understand the present invention, the preferred embodiments of the present invention will be described below in conjunction with examples.

[0026] In the present invention, a small amount of volatile solvent is added, and the volatile components and higher boiling point components are separated through an ultrafiltration membrane; the solvent consumption is small, which has the effect of separating and enriching the target analyte; the external standard method directly introduces the GC- MS or ion chromatography detects the content of volatile components. In the present invention, the solvent should meet the basic requirements of the GC-MS chromatograph or ion chromatograph that can be directly injected into the sample; the solvent is a low-boiling substance that does not exist in the sample to be tested; the solvent has good compatibility with the tested component, but is polar The difference should not be too si...

Abstract

The invention provides a method for detecting volatile components in a water-based glue for cigarette. The method concretely comprises the following steps: weighing M1 g of a water-based glue sample,performing membrane filtration on the water-based glue by an ultrafilter membrane, cleaning the ultrafilter membrane with M2 g of anhydrous ethanol or DMF, collecting the obtained filtrate and cleaning solution to obtain a solution to be detected, taking and injecting 1 mL of the solution to be detected into a chromatographic bottle, analyzing the solution to be detected through a gas chromatograph-mass spectrometer to obtain data of various detected components in the sample to be detected, calculating the content W2 of all the detected components in the sample to be detected according to a standard curve, and multiplying the content W2 by a corresponding dilution ratio (M1 + M2)/M1 to obtain the content W1 of all the detected components in the original water-based glue sample, wherein 3M1< M2 < 5M1. The method can be used for detecting various volatile substances in the water-based glue, can provide the quantification information of volatile chemical components affecting the sensoryquality of the cigarette in the water-based glue sample, and has good practical values.

Description

technical field [0001] The invention relates to a chromatographic detection method through the separation and quantitative analysis of the volatile components of the water-based glue of the cigarette tipping paper ink raw material, including headspace-mass chromatography and ion chromatography. Background technique [0002] Adhesives are additives made of film-forming materials that can be dispersed or dissolved in water. Film-forming materials are generally organic polymers, animal glue, starch, dextrin, serum albumin, albumin, methylcellulose and polyvinyl alcohol are all such adhesives, and there are some soluble intermediates of phenolic and urea-formaldehyde resins. bodies also fall into this category. Some adhesive film-forming materials can be dissolved or dispersed in water by means of alkaline solution. Examples of this type include casein, rosin, shellac, carboxyl-containing vinyl acetate or acrylate copolymers (such as crotonic acid, methyl acrylic acid or malei...
