example 1

[0033] 1. Instruments and reagents:

[0034] Pentachlorophenol, methanol, and acetic acid are chromatographic grade reagents; distilled water meets the requirements of first-grade water in GB / T 6682.

[0035] API 4000 quadrupole tandem mass spectrometer; Swiss Mettler AE 163 electronic balance (sensitivity: 0.0001g).

[0036] 2. Sample handling:

[0037]Cut the sample first: the cutting method of tipping paper for cigarettes shall be carried out in accordance with the regulations of YC 171-2008, that is, to accurately cut a sample of tipping paper with a length of 200 mm and a width of 40 mm (should include a single side); The final sample was placed on a balance and weighed; then the sample was cut into fragments no larger than 0.5 cm × 0.5 cm with scissors; the fragments were placed in a 50 mL Erlenmeyer flask with a stopper, and 40 mL of extract and 50 μL of internal standard solution were added accurately (2,4,5-T, 1.0 μg / mL), ultrasonic extraction for 30 min; stand st...

example 2

[0043] As described in Example 1, another tipping paper sample for cigarettes was selected, and the content of pentachlorophenol in the sample was measured to be 0.

Abstract

A measurement method for the residual amount of pentachlorophenol in cigarette paper is characterized by comprising the following steps: cutting cigarette paper into pieces, adding extract liquor into the pieces, conducting ultrasonic extraction and measuring the residual amount of pentachlorophenol in the cigarette paper with liquid chromatography-tandem mass spectrometry (LC-MS / MS) directly after centrifugation of the extract liquor. The method comprises the following steps: a. cutting a cigarette paper sample according to relevant regulations; b. extracting a sample; c. purifying the sample; d. preparing a standard operating solution; e. carrying out liquid chromatography-tandem mass spectrometry (LC-MS / MS) measurement; f. calculating the measured result of the residual amount of pentachlorophenol. In comparison with the prior art, the measurement method has the following advantages: 1. adopting a pre-treatment of cutting the sample to make a solvent contact the sample better. The experiment result shows that such treatment can help to increase the extraction efficiency of pentachlorophenol. 2. measuring the content of pentachlorophenol in the paper with LC-MS / MS without derivatization operation, and the pre-treatment method is simple. 3. The method is accurate in operations, high in sensitivity and good in repeatability.

Description

technical field [0001] The invention belongs to the technical field of physical and chemical inspection of harmful substance residues in cigarette paper, and mainly relates to a method for measuring the residual amount of pentachlorophenol in cigarette inner liner paper, tipping paper, and carton wrapping paper, specifically a method using ultrasonic extraction Pentachlorophenol, a method for direct determination by liquid chromatography-tandem mass spectrometry. Background technique [0002] In the production process of paper including lining paper, tipping paper, carton wrapping paper, etc., various chemicals such as bleaching agents, processing aids, printing inks, antiseptics and bactericides need to be added to improve its quality. Packaging performance and aesthetics. However, studies have found that these chemicals will remain in paper and then migrate into cigarettes, some of which are toxic or even carcinogenic, posing a hazard to consumers' health. Developed coun...
