An analytical method for the determination of ethyleneglycol monoalkyl ethers and esters in plastics products in contact with foodstuffs by Ultrasonic Extraction-GC-MS has been established.. Samples are extracted by using methanol and purified with the silica gel column. The analyte was detected by GC-MS. The detection limit of method is 10mg/kg, the recoveries are is the range of 80%~95%, and the relative standard deviations(RSD)are no more than 6%. The standard curves for ethyleneglycol monoalkyl ethers and esters was linear in the concentration range of 10mg/L~1000mg/L.
