Objective To establish a method for determination of diphenyl ether in food packing materials using gas chromatography/mass spectrometry. Methods The diphenyl ether in food packing materials was ex-tracted by soxhlet extraction with dipropyl ether, and then qualitatively anlyzed using mass spectrometry detector. The diphenyl ether were qualitatively determined by retention time and molecular fragment peaks. The external standard method was applied for the quantification. Results The recoveries of typical diphenyl ether were be-tween 88%~109%with RSD less than 3.9%and limit of detection was 0.032~0.067 mg/L. Conclusion The me-thod is convenient and reproducible for determination of diphenyl ether from the food packing materials.
