AB  - An ultra performance liquid chromatography-quadrupole/electrostatic field 
      orbitrap high resolution mass spectrometry (UPLC-Q Orbitrap HRMS) method was 
      developed for the rapid determination of 48 contaminant residues in food plastic 
      packaging materials. The samples were extracted with methanol using 
      microwave-assisted extraction. The separation of the 48 contaminants was 
      performed on a CAPCELL PAK MG Ⅱ C18 column (150 mmx2.0 mm, 5 mum) with gradient 
      elution. Methanol (containing 0.04% (v/v) formic acid) and water (containing 
      0.04% (v/v) formic acid and 20 mmol/L ammonium acetate) were used as mobile 
      phases. The compounds were detected under the full scan/date dependent-MS/MS 
      (Full MS/dd-MS(2)) mode with a heated electrospray ionization (HESI) source. The 
      calibration curves were linear with correlation coefficients no less than 0.9950. 
      The limits of detection (LODs) ranged from 0.1 to 1.0 mug/kg. The average spiked 
      recoveries of the 48 target compounds were between 71.2% and 108.8%, with 
      relative standard derivations (RSDs) ranging from 2.2% to 11.8% (n=6). Compared 
      to previous methods, this method has advantages of simpler sample preparation and 
      higher sensitivity.
