Determination of volatile organic compounds VOCs in packaging materials

Stationary phase: polyethylene glycol
Specification: 60m*0.32mm*0.25um
Model: HH-INNOWAX
Application: SNT 4148-2015 Determination of Volatile Organic Compounds (VOCs) in Packaging Materials - Static Headspace - Gas Chromatography
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. established a gas chromatography-mass spectrometry method for simultaneous determination of 32 volatile organic compounds (VOCs) in food packaging materials. The method was to set the equilibrium temperature and time to 100 °C and 30 min respectively. The column was HP-VOC, the carrier gas was helium, the flow rate was 2.0 mL/min, and the split-flow injection was performed. The inlet temperature was 250 °C. For programming. Quantitative analysis was performed using an external standard method. Results The detection limit of the method was in the range of 0.01~0.17 mg/m2, the correlation coefficient was >0.99, the recoveries of the samples were 90.3%~109.9%, and the relative standard deviations were 1.1%~8.9% (n=6). Conclusion This method is suitable for the testing of volatile organic compounds in food packaging materials.
