This experiment established an effective analytical method for the simultaneous determination of the migration amount of 12 ester monomers including acrylic esters and metacrylic acid esters in food contact materials by gas chromatography (GC). Using water, 3% acetic acid, 10% ethanol and olive oil soaked food contact materials, the obtained aqueous food simulants (water, 3% acetic acid, 10% ethanol) and olive oil simulant were treated at 80 ℃ and 90 ℃ respectively for 20 min, then separated on a DB-624 column (30 m×0.32 mm×1.8 μm) for headspace injection analysis with hydrogen flame ionization detector for qualitation by time retention and quantitation by peak area． The results showed a good linear correlation in the range of 0.05~10 mg/L (aqueous food simulants) and 0.1~50 mg/kg (olive oil simulant) with correlation coefficients above 0.999. The recovery of the ester compounds spiked in the sample and the relative standard deviation were 89.3% ~109.6% and 1.13% ~7.55% respectively. The method was simple with good separation and high analytical sensitivity, and met the analysis requirements of migration of the 12 acrylate monomers in food contact materials.
