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

[0053]In order to determine the accuracy of the detection method provided by the application and determine the detection limit, in the present embodiment, the applicant prepared 5 gradient standard working solution concentrations with different types of citrate plasticizers. The concentration of the standard 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:

[0054] Gas chromatography conditions:

[0055] Adopt HP-5MS type 60m×0.25mm×0.25μm quartz fused capillary column;

[0056] Injection volume 1μL; carrier gas: He; flow rate: 1mL / min;

[0057] The inlet temperature is 280°C;

[0058] 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;

[0059] Mass Spectrometry Conditions:

[0060] Electron bo...

Embodiment 2

[0086] 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.

[0087] (1) About the choice of extraction solvent

[0088] 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 plasticizer content in the extraction solution was measured, and the results are shown in the table below:

[0089]

[0090] The measurement results show that when dichloromethane is used as the extractant, the content of plasticizer in the extract is the highes...

Embodiment 3

[0115] 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.

[0116](1) Pretreatment of cigarette paper packaging material samples

[0117] 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;

[0118] (2) Extraction and separation

[0119] The dichloromethane solution of benzyl benzoate is used as the extractant to extract the mixed solution of step (1). After the extraction, the citrate plasticizer is extracted into the upper layer of n-hexane extraction solution, and the deionized Water and paper packaging material samples are distributed in the lower solution;

[0120] In terms of specific dosage, the mixed solution in step (1): extractant = 0.25g: 15mL;

[0121] The dichloromethane solution concentrati...

Abstract

The invention belongs to the technical field of the detection of related substances in cigarette materials and particularly relates to a method for detecting non-phthalate plasticizers specifically citrate plasticizers in the paper packaging material for cigarettes. The method mainly includes: pretreating a paper packaging material sample for cigarettes, extracting and separating, drying and filtering, performing gas chromatography-mass spectrum automatic detection and analysis and the like. The method has the advantages that the related extraction time, extraction conditions and detection method are optimized in a targeted manner, and a weak-polarity capillary chromatographic column is selected in a targeted manner to allow the target compound in a detection result to be good in peak shape and good in separation degree; in general, the related operation steps of the method are easy to unify and standardize, and the method is low in time consumption, capable of simultaneously detectingvarious substances in one step, good in repeatability, high in sensitivity and the like; accordingly, the method has quite important application significance to the detection and control of the content of the related plasticizers in the paper packaging material for 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 detection method for non-ortho-phenyl ester plasticizers in paper packaging materials for cigarettes, specifically citrate plasticizers. 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 differ...
