Determination of Styrene in Polystyrene Tableware by Headspace Gas Chromatography

Residues of styrene in polystyrene tableware were analyzed by headspace gas chromatography. The standard curve was used for quantitative determination. Under the selected conditions the contents of styrene are linearly related to their peak areas in the range of 5.0-1000mg/L.The detection limit is lower then 0.1mg/L. The method is convenient, rapid and the results are well repeatable.
