[Headspace GC/MS Analysis of Residual Solvents in Laminated Films Used for Food Packaging]. Shokuhin Eiseigaku Zasshi. 2019;60(4):73-81 Authors: Ozaki A, Kishi E, Ooshima T, Kakutani N, Abe Y, Mutsuga M, Yamano T Abstract Multilayer laminated films may contain organic solvents derived from adhesives, printing inks and so on. A headspace-GC/MS analysis method for the simultaneous determination of 30 substances such as toluene, xylene, acetone, methyl ethyl ketone, ethyl acetate, butyl acetate, methanol, ethanol, was developed. A N,N-dimethyl formamide solution containing an internal standard substance was added to the sample. After leaving overnight at room temperature, the headspace gas was analyzed by GC/MS. This method was applicable to a laminate film made of various materials. The organic solvents such as toluene, ethyl acetate, and heptane were detected from 6 out of 42 food packaging bags made from laminated film on Japanese market using this method.
