This Technical Report lists mass spectrometric parameters which are useful for the application of European Standards for the determination of pesticide residues in foods that use GC-MS, such as the following standards:
  • ― EN 1528 (all parts), Fatty food — Determination of pesticides and polychlorinated biphenyls (PCBs);
  • ― EN 12393 (all parts), Foods of plant origin — Multiresidue methods for the gas chromatographic determination of pesticide residues;
  • ― EN 15662 , Foods of plant origin — Determination of pesticide residues using GC-MS and/or LC-MS/MS following acetonitrile extraction/partitioning and clean-up by dispersive SPE — QuEChERS-method.
To facilitate the determination of pesticides and/or metabolites using GC-MS, Table 1 specifies the diagnostic ions suitable for quantification, which can be used.
