AB  - A method was developed for the determination of the residue of phenylethanolamine 
      A in feeds by ultra performance liquid chromatography-triple quadrupole mass 
      spectrometry (UPLC-MS/MS). The phenylethanolamine A in sample was extracted with 
      phosphoric acid methanol solution. The extract was purified and concentrated by 
      an MCX column. In the positive mode, an ultra-performance BEH C18 column (100 mm 
      x 2.1 mm, 1.7 microm) was used to separate the phenylethanolamine A, and the 
      separation was carried out on a Waters UPLC system by using gradient elution with 
      acetonitrile and 0.1% (v/v) formic acid aqueous solution as the mobile phases at 
      a flow rate of 0.4 mL/min. The qualitative and quantitative analysis was carried 
      out by multi-reaction monitoring (MRM) mode, in which the analyte was ionized by 
      electrospray ionization interface (ESI). The results showed that, the calibration 
      curve was linear in the range of 0.5-100 microg/kg (r > 0.999), the limit of 
      quantification (S/N > 10) was 10 microg/kg, the recoveries ranged from 79.6% to 
      86.2%, and the relative standard deviations (RSDs) were between 3.1% and 6.7%. 
      The real sample tests showed that the method is convenient and reliable.
