Headspace Gas Chromatographic Analysis of Residual Volatile Substances in Polystyrene Food Containers
1995
Shokuhin Eiseigaku Zasshi
A headspace gas chromatographic method was developed for the determination of residal volatile substances (toluene, ethylbenzene, isopropylbenzene, n-propylbenzene and styrene) in food containers made of polystyrene (PS). A PS sample (0. 20 g) was weighed into a vial and 1. 0 ml of N, N-dimethylformamide (DMF) as a solvent and 0. 5 ml of p-diethylbenzene in DMF as an internal standard substance were added. The vial was kept in an oven for 1 hour at 90C, then 0. 5 ml of headspace gas was
