[0015] 2. Preparation of samples to be tested

[0016] After shaking the ink sample evenly, use a 100 μL pipette gun to pipette 1 drop of the sample into a 20 mL headspace bottle, read the weight, accurate to 0.001 g, add 100 μL matrix corrector triacetin, and seal it for testing.

[0017] 3. Instruments and conditions

[0018] 1) Static headspace instrument conditions

[0019] Sample equilibration temperature 85°C; sample loop temperature 105°C; transfer line temperature 125°C. ; Sample equilibrium time 48min; sample bottle pressurization pressure 138kPa; pressurization time 0.2min; inflation time 0.2min; sample loop equilibrium time 0.05min;

[0020] 2) Gas chromatography conditions

[0021] The chromatographic column is a VOC capillary column with a specification of 60m×0.32mm×1.8μm; the carrier gas is helium; the inlet temperature is 160°C; the split ratio is 20:1; the column flow rate is 2.0mL / min; ℃, keep for 2min, then increase to 180℃ at the rate of 4℃ / min, and the...

Embodiment 1

[0042] Select one ink sample for black, red and brown cigarette tipping paper respectively, shake the ink samples evenly, pipette 1 drop of the sample into a 20mL headspace bottle with a 100μL pipette gun, and read the weight. Accurate to 0.001g, add 100 μL matrix corrector glycerol triacetate, seal and perform headspace gas phase detection. The measurement conditions are as follows:

[0043] Static headspace instrument conditions: sample equilibrium temperature 85°C; sample loop temperature 105°C; transfer line temperature 125°C. ; Sample equilibrium time 48min; sample bottle pressurization pressure 138kPa; pressurization time 0.2min; inflation time 0.2min; sample loop equilibrium time 0.05min;

[0044] Gas chromatography conditions: the chromatographic column is a VOC capillary column, the specification is 60m×0.32mm×1.8μm; the carrier gas is helium; the inlet temperature is 160°C; the split ratio is 20:1; the column flow rate is 2.0mL / min; : The initial temperature is 40°...

Abstract

The invention relates to a method for detecting the contents of 22 kinds of volatile organic compounds in cigarette tipping paper printing ink, including benzene, toluene, ethylbenzene, ortho / meta / para-xylene, phenethylene, methanol, ethanol, isopropyl alcohol, n-propyl alcohol, n-butanol, acetone, 4-methyl-2-pentanone, butanone, cyclohexanone, ethyl acetate, n-propyl acetate, n-butyl acetate, isopropyl acetate, 1-methoxy-2-propyl alcohol and 1-ethoxy-2-propyl alcohol. Detection is performed by headspace gas chromatography by taking glyceryl triacetate as a matrix rectifier. According to the method provided by the invention, a sample pretreatment process is simple, the automation degree of the whole operation is high, the simultaneous detection of various volatile organic compounds can be realized, and the detection sensitivity, the recovery rate and the result precision are high.

Description

technical field [0001] The invention relates to a method for measuring volatile organic compounds in ink used for cigarette tipping paper, and belongs to the technical field of physical and chemical inspection of raw and auxiliary materials for cigarette packaging. Background technique [0002] Tobacco is a special food-grade product, and the country's requirements for the safety and health indicators of the tobacco industry are also increasing day by day. Volatile organic compounds (VOCs) are class A indicators in the safety and hygiene indicators, and the raw and auxiliary materials of cigarette packaging need to be inspected. Cigarette tipping paper is an important part of cigarette materials, and it directly contacts consumers' lips Therefore, the safety and health indicators are strictly monitored. At present, the research objects of volatile organic compounds in cigarette packaging materials mainly focus on the paper of tipping lining for cigarettes, that is, the resi...
