Problems solved by technology

[0007] For water-based adhesives used in cigarettes, the sample processing methods and chromatographic conditions summarized in existing studies are not reasonably pertinent. At present, there is a lack of water-based adhesives for cigarettes that can simultaneously detect multiple benzene series in one sample injection. Technical research and technical reports related to phthalates

Embodiment 1

[0055] S1. Preparation of standard working solution:

[0056] The standard products of benzene series are benzene, toluene, ethylbenzene, o-xylene, m-xylene and p-xylene, and the standard products of phthalates are dimethyl phthalate (DMP), phthalate Diethyl formate (DEP), diisobutyl phthalate (DIBP), dibutyl phthalate (DBP), butyl benzyl phthalate (BBP), di( 2-Ethyl)hexyl ester (DEHP), dioctyl phthalate (DNOP), prepared into a mixed standard solution by serial dilution;

[0057] S2. Preparation of sample solution: Weigh and accurately weigh 0.3g (accurate to 0.0001g) of tobacco hydrosol (each experiment is randomly selected from commercially available tobacco hydrosol samples, and does not therefore limit the scope of the present invention). Put the sample in a 25mL Erlenmeyer flask with a stopper, add 2mL ultrapure water, and add 10mL containing 0.4μg / mL 2-hexanone (internal standard of benzene series) and 0.15μg / mL benzyl benzoate (phthalate) after the sample is dispersed....

Abstract

The invention discloses a method for simultaneous detection of 13 benzene compounds and phthalic acid ester compounds in a water-borne adhesive. The method comprises the steps of oscillating to disperse samples by adopting ultrapure water, then extracting through cyclohexane and filtering to obtain a sample solution, and simultaneously detecting 13 compounds in the water-based adhesive for cigarettes in one-time sample feeding by utilizing a gas chromatograph-mass spectrometer. The chromatographic peak has good separation effect, and the result shows that the correlation coefficients of the regression equation of components all reach 0.997 or above, the quantitative detection limits of six benzene compounds are 0.04-0.07 microg / g, and the quantitative detection limits of seven phthalic acid ester compounds are 0.5-4.2 microg / g. The method has the advantages of accuracy, rapidness, high sensitivity, good repeatability, high recovery rate and the like, and conforms to the quantitative requirement.

Description

technical field [0001] The present invention relates to the technical field of detection of tobacco water-based glue, more specifically, relates to a method for simultaneously measuring 13 kinds of benzene series and phthalate compounds in water-based glue and its application in the detection of tobacco water-based glue . Background technique [0002] Water-based adhesive is a water-soluble or emulsion-type adhesive with water as the dispersion medium. It is mainly used in cigarette manufacturing industry for cigarette joints, cigarette mouthpieces, filter rod centerlines, and cigarette packaging. In the process of producing water-based glue, some benzene series, phthalates and other substances may be introduced due to raw materials or operating process problems. The national tobacco industry has particularly strict quality control on water-based adhesives. It has set corresponding limit regulations on the possible residual benzene series and phthalates, and formulated corr...
