Fund Project: This work was supported by the Science and Technology Plan of General Administration of Quality Supervision, Inspection and Quarantine of the People`s Republic of China (No. 2015QK162).

A high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (HPLC-Q-TOF/MS) method for determination of seven kinds of alkylamines was established. Samples were amidated with 0.4% benzyl chloroformate (Cbz-Cl) in acetonitrile-sodium carbonate solution (50:50, V/V). The amidated conditions, including concentration of sodium carbonate solution (1.5%, m/V), benzyl chloroformate ratio and amount of sodium chloride (1.5 g), were optimized by response surface methodology. Under the optimized chromatographic and mass spectrometer conditions, the data were collected with electrospray ionization (ESI) sources under positive ion mode. The calibration curves of seven kinds of alkylamines showed good linearity in concentration range of 1.0-500 μg/L(R²>0.9957). The average recoveries were 82.0%-108.0%, the limits of detection and quantification were 0.5-1.0 μg/kg and 2.0-4.0 μg/kg, respectively, and the relative standard deviations (RSDs) were 3.5%-6.8%. This method is efficient and easy to be operated, and has good sensitivity, high precision and accuracy in the determination of seven alkylamines in food contact plastic materials.
