Food analysis. Determination of pesticide residues by GC-MS. Retention times, mass spectrometric parameters and detector response information
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.
