Screening and Identification of Potential Risk Components in Packaging Materials Using HS-SPME-GC-MS Method
Based on gas chromatography-mass spectrometry(GC-MS),the detection and analysis effects of headspace solid-phase microextrac-tion gas chromatography-mass spectrometry(HS-SPME-GC-MS)and headspace gas chromatography-mass spectrometry(HS-GC-MS)on vol-atile substances in paper printing packaging materials were compared.The extraction head,equilibrium temperature,and extraction time con-ditions of HS-SPME-GC-MS were optimized.Fourteen small box packaging materials and fourteen strip box packaging materials were used as research objects to determine their volatile substances.Qualitative analysis of volatile components was conducted based on the NIST17 spec-tral library,and volatile risk components were compared,screened,and identified.The HS-SPME-GC-MS method was selected for the analysis of paper printing packaging materials,and the extraction head,equilibrium temperature,and extraction time conditions were optimized.A total of 231 volatile compounds were detected,including 22 volatile risk components,including 4 controlled compounds such as biphenyl,2-methyl-naphthalene,1-decene,1,2,4,5-tetramethylbenzene,and 18 toxic compounds such as dipropenyl phthalate,undecane,1-methylnaphthalene,2-ethylhexyl acetate,and 4-methoxyphenol.After undergoing tedious and complex processes,packaging materials can be identified by head-space solid-phase microextraction gas chromatography-mass spectrometry to contain small amounts of volatile risk components that are harmful to human health.
