| Abstract: |
| A gas chromatography-tandem mass spectrometric（GC-MS/MS）method was developed for the determination of 9 volatile perfluorinated compounds precursors including perfluorinated fatty alcohol，perfluorinated fatty alcohol acrylate and perfluorosulfonamide fatty alcohol，using 3% acetic acid，10% alcohol，50% alcohol，and olive oil as food simulants according to（EU） 2017/752.The water-based and olive oil simulants were extracted with dichloromethane and acetonitrile，respectively.The volatile perfluorinated compounds precursors were separated on a DB-5MS（30 m×0.25 mm×0.25 μm）column，and analyzed under multiple reaction monitoring mode.The cailbration curves for 9 analytes were linear in the range of 5-500 μg/L，with the quantitation limits of 3.3-4.4 μg/L for 3% acetic acid，3.5-4.2 μg/L for 10% alcohol，3.3-4.9 μg/L for 50% alcohol and 4.2-5.1 ng/g for olive oil，respectively.The spiked recoveries for the samples ranged from 85.0% to 115% with the relative standard deviations（RSDs）not more than 7.8%.This method was fast，precise and convenient，and was appropriate for the determination of 9 perfluorinated compounds precursors in food-contact paper based materials. |
