PD CEN/TR 16699:2014CEN/TR 16699:2014 (E) 4 Introduction Pesticide residues analysis employs multi methods involving extraction of residues from the homogenized sample and clean-up of the extract in order to determine as many components as possible in the extracts. Afterwards the extracts can
12、 be analysed by different kind of instruments. The hyphenation of gas chromatography (GC) and tandem mass spectrometry (MS/MS) is a highly selective technique for identification and quantification of pesticide residues in extracts of plant and animal origin. This technique may be used to replace GC-
13、MS detection in existing methods without the need for additional validation provided that calibration was successful and has demonstrated the required sensitivity and precision. For the ionization of the analytes (pesticides and/or their metabolites) in GC-MS/MS, electron impact ionization (EI) is w
14、idely used because it offers sufficient ionization of most compound classes. However, very often molecular ions (cation radicals) and several fragment ions are formed simultaneously. For that reason, a rich variety of potential parent ions for MS/MS transitions exists compared to the soft ionization
15、 techniques applied in LC-MS/MS. This results in a greater freedom for the selection of an appropriate transition for a given situation. Such freedom is useful and often necessary in GC-MS/MS because a higher number of (fragment) ions are often produced by the matrix, which may interfere with the si
16、gnal of the target analyte. On the other hand, this higher number of options may be a bit confusing for less experienced analysts. To simplify the selection of suitable GC-MS/MS transitions in that situation, this Technical Report lists those MS/MS transitions, which have been reported most often in
17、 the scientific literature or are most often proposed by suppliers of GC-MS/MS instruments. PD CEN/TR 16699:2014CEN/TR 16699:2014 (E) 5 1 Scope This Technical Report lists the mass spectrometric parameters which are useful for the application of European Standards for the determination of pesticide
18、residues in foods of plant origin that use GC-MS.

21、, application notes of instrument providers or tested by experts of CEN/TC 275/WG 4). Only transitions that were applicable on instruments of at least two different manufacturers (e.g. Agilent Technologies, Bruker Daltonics, Thermo Scientific, former Varian Inc., Waters Corporation) were selected.

23、 Parameters All listed MS/MS transitions were obtained from measurements with electron impact ionization at 70 eV.
