Problems solved by technology

[0005] Generally speaking, the current main determination method for the detection of plasticizers is the method of gas chromatography-mass spectrometry, but due to the different properties of different plasticizers, there is no relatively unified and general method, and therefore, for When testing and measuring different types of plasticizers, it is necessary to redesign the detection method in a targeted manner

Embodiment 1

[0055] In order to determine the accuracy of the detection method provided by the application and to determine the detection limit, in this embodiment, the applicant prepared 5 gradient standard working solution concentrations with different types of phosphate plasticizers. The concentration of the working solution was automatically detected and analyzed by gas chromatography-mass spectrometry; when detecting and analyzing, the specific reference settings of the instrument parameters are as follows:

[0056] Gas chromatography conditions:

[0057] Adopt HP-5MS type 60m×0.25mm×0.25μm quartz fused capillary column;

[0058] Injection volume 1μL; carrier gas: He; flow rate: 1mL / min;

[0059] The inlet temperature is 280°C;

[0060] Programmed heating conditions: 100°C, keep for 2 minutes, rise to 200°C at 20°C / min, then rise to 280°C at a rate of 5°C / min, hold for 10 minutes, and run at 300°C for 5 minutes;

[0061] Mass Spectrometry Conditions:

[0062] Electron bombardment ...

Embodiment 2

[0088] Since the extraction of the plasticizer in the cigarette paper packaging material sample has an important impact on the subsequent experimental detection, this embodiment briefly introduces the partial orthogonal experimental processing of the relevant sample pretreatment as follows.

[0089] (1) About the choice of extraction solvent

[0090] The paper packaging material (frame paper) used in the cigarette processing process was used as the test sample, and 1.0g was sampled as the test sample. Different polar solvents were used as extraction agents, and 60 mL of extraction agents were added, and the extraction operation was performed by ultrasonication for 40 minutes. After the extraction was completed, the content of plasticizer in the extraction solution was measured. The measurement results showed that when dichloromethane was used as the extractant, the content of plasticizer in the extract was the highest. Therefore, dichloromethane was the most suitable as the ex...

Embodiment 3

[0099] Based on the optimization of related operations in Example 2, specific tests are carried out in this example, and the relevant experimental process is briefly introduced as follows.

[0100] (1) Pretreatment of cigarette paper packaging material samples

[0101] Select a sample of cigarette paper packaging material (tipping paper), cut it into pieces (with an area not exceeding 5mm×5mm), weigh 0.25g and place it in a 25mL Erlenmeyer flask with a stopper;

[0102] (2) Extraction and separation

[0103] The dichloromethane solution of benzyl benzoate is used as the extractant, and the extraction operation is carried out in the mixed solution of step (1). After the extraction, the phosphate plasticizer is extracted into the upper layer n-hexane extraction solution, and the deionized water and paper packaging material samples are distributed in the lower solution;

[0104] In terms of specific dosage, the mixed solution in step (1): extractant = 0.25g: 15mL;

Abstract

The invention belongs to the technical field of detection of relevant substances in cigarette materials, and particularly relates to a method for detecting the content of non-phthalate ester plasticizers, particularly a phosphate ester plasticizer, in paper packaging materials for cigarettes. The method mainly comprises the steps of pretreatment of samples of the paper packaging materials for thecigarettes, extraction separation, drying and filtering, gas chromatography, mass-spectroscopy automatic detection and analysis and the like. By means of the method, the relevant extraction time, theextraction condition and the detection method are targetedly optimized, and by targetedly selecting weak-polarity capillary chromatographic columns, a target compound in the detection result is good in peak shape and good in resolution. In general, the relevant operation steps of the detection method are easily unified and standardized; besides, thanks to the technical advantages that the consumedtime is short, multiple substances can be detected simultaneously at a time, the repeatability is good and the sensitivity is high, the method has very important application significance in detectingand controlling the content of relevant plasticizers in the paper packaging materials for the cigarettes.

Description

technical field [0001] The invention belongs to the technical field of detection of related substances in cigarette materials, and in particular relates to a method for detecting non-ortho-phenyl ester plasticizers, in particular phosphate plasticizers, in paper packaging materials for cigarettes. Background technique [0002] In the production process of cigarettes, paper packaging materials for cigarettes are mainly involved in the rolling and packaging of cigarettes, including cigarette paper, tipping paper, forming paper, frame paper, box wrapping paper and strip wrapping paper. Cigarette paper is a kind of thin sheet paper specially used for wrapping tobacco to make cigarettes. It is mainly divided into straight rib cigarette paper, horizontal rib cigarette paper and anti-counterfeiting cigarette paper; tipping paper is also called tipping paper, which is used for The paper that wraps the filter tip and bonds the filter rod to the end of the tobacco rod. According to di...
