Trace detection of organophosphorus pesticides in vegetables via enrichment by magnetic zirconia and temperature-assisted ambient micro-fabricated glow discharge plasma desorption ionization mass spectrometry

The use of Fe 3 O 4 /ZrO 2 eliminates the steps of centrifugation and cleanup. The introduction of TCS improves the problem of low desorption efficiency in MFGDP-MS. This method has been proved to be a good pesticide residue detection method.
