Example Embodiment

[0060] Example 1

[0061] 1. Preparation of the sample

[0062] The sample of cigarette packaging paper is cut into a certain area, and the cutting area should include the main packaging surface. When the cigarette wrapping paper is hard box wrapping paper or strip wrapping paper, the cutting area is length×width=22cm×5.5cm; when the cigarette wrapping paper is soft box wrapping paper, the cutting area is length×width=15.5cm× 10cm. The cut tobacco packaging paper sample is rolled into a cylindrical shape with the printing side facing inward and placed in a headspace bottle, and 100-2000 μL of triacetin, preferably 1000 μL is added, as a test sample, and sealed for testing.

[0063] 2. Preparation of standard samples

[0064] Take the base paper corresponding to the cigarette packaging paper sample and cut it into a certain area. The cutting area of ​​the hard box packaging paper base paper or the strip packaging paper base paper is length×width=22cm×5.5cm; the cutting area of ​​soft...

Example Embodiment

[0073] Example 2

[0074] Prepare the base paper standard sample of hard box packaging paper as shown in step 2 of Example 1, and perform headspace-gas chromatography / mass spectrometry (HS-GC / MS) detection according to step 3 of Example 1. The standard sample contains glycol ethers The headspace-gas chromatography / mass spectrogram of the substance is as figure 1 Shown. Take the quantitative ion peak area of ​​glycol ether substances as the ordinate (Y axis), and its corresponding content (based on the mass number of the target compound contained in the hard box packaging paper per unit area, mg / m 2 ) Is the abscissa (X axis), linear fitting is performed, and a standard working curve is established. The standard working curve is not forced to cross the origin. The retention time, standard working curve equation and coefficients (R 2 ), the linear concentration range is shown in Table 2. It can be seen from Table 2 that the coefficient R of the standard working curve 2 ≥0.995, go...

[0077] Example 3

[0078] Take a hard box packaging paper sample of a certain brand according to step 1 in Example 1 to cut two parallel samples, roll the cut hard box packaging paper sample into a cylinder with the printed side facing inward and put them into the headspace bottle, respectively Add the same volume of glycerol triacetate and seal for testing. The sample prepared above was subjected to headspace-gas chromatography / mass spectrometry determination in step 3 of Example 1, and the average value of two parallel determinations was taken as the analysis result of the glycol ether substance in the brand hard box packaging paper sample. Two decimal places, see the specific test results figure 2 . by figure 2 As shown, the hard box packaging paper sample contains 2-ethoxyethanol and 2-butoxyethanol.

Abstract

The invention provides a method for measuring a glycol ether substance in package paper for a cigarette. The method specifically comprises the following steps of 1), preparation of a test sample; 2), preparation of a standard sample; 3), sample detection: subjecting the test sample and the standard sample to head space-gas chromatographic/mass spectrometric measurement respectively, so as to obtain total ion current chromatograms and selected ion chromatograms of the test sample and the standard sample; 4), qualitative analysis: by using retention time and a fragment ion peak of the glycol ether substance in the total ion current chromatogram of the standard sample as references, determining the glycol ether substance existing in the test sample; 5), quantitative analysis: establishing a standard working curve through the content of glycol ether in the standard sample and the selected ion monitoring chromatogram of the standard sample, and carrying out quantification by an external standard method, so as to obtain the content of the glycol ether substance in the test sample. The method for measuring the glycol ether substance in the package paper for the cigarette, which is provided by the invention, is high in sensitivity and good in repetitiveness and recovery rate; an effective technical means is provided for the qualitative and quantitative analysis of the glycol ether substance in the package paper for the cigarette.

Description

technical field [0001] The invention belongs to the technical field of tobacco detection, and relates to a method for measuring glycol ether substances in cigarette packaging paper. Background technique [0002] Ethylene glycol ether is an important derivative of ethylene oxide, which is widely used. It is often used as a cosolvent for inks and adhesives, and can also be used as a stabilizer, thinner, paint remover, cleaner, antifreeze, etc. Glycol ether has certain toxicity, water solubility and volatility, which can cause environmental pollution and is listed as a substance of very high concern. Cigarette wrapping paper includes cigarette box wrapping paper (hard box, soft box) and strip wrapping paper. In the production and printing process, ink, thinner, stabilizer, etc. are commonly used. If there is glycol ether residue, it will adversely affect product quality and safety. [0003] At present, the analysis of glycol ether substances in cigarette sticks and box wrappi...
