PD CEN/TR 16699:2014 CEN/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. After
12、wards the extracts can 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
13、be used to replace GC-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 impac
14、t ionization (EI) is widely 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
15、to the soft ionization 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
16、 interfere with the signal 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
17、reported most often in the scientific literature or are most often proposed by suppliers of GC-MS/MS instruments. PD CEN/TR 16699:2014 CEN/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 dete
18、rmination of pesticide residues in foods of plant origin that use GC-MS.

20、e diagnostic ion transitions suitable for identification and quantification, which can be used. 2 Normative References None. 3 Parameters for GC-MS/MS determination of pesticides following electron impact ionization 3.1 General All parameters given in Table 2 were carefully selected from different s
21、ources (open literature, 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 Corpor
22、ation) were selected. GC parameters and retention times are not described in this Technical Report. If needed, this information can be taken from CEN/TR 16468 “Food analysis - Determination of pesticide residues by GC-MS - Retention times, mass spectrometric parameters and detector response informat
23、ion“. 3.2 General MS/MS Parameters All listed MS/MS transitions were obtained from measurements with electron impact ionization at 70 eV. Other parameters (e.g. ion source temperature, ion source voltages, source pressure and the type of carrier gas) were not identical. It is well recognized that va
24、riations of these parameters may influence the intensity of selected precursor ions and individual optimization may be necessary. However, despite these differences very often the same preferred precursor ions were reported. This demonstrates that in many cases parameters can be transferred between
25、instruments of other types of the same or other manufacturers, even if these instruments are operated under slightly different conditions. 3.3 Analyte specific MS/MS Parameters The most often reported analyte specific ion transitions of pesticides are listed in Table 2. Transitions applicable for in
26、struments of three suppliers are reported first and those transitions reported for instruments of two suppliers are written in italics. If available, at least two precursor ions with their transitions have been selected for each analyte. In general, transitions starting from ions with higher mass we
27、re preferred to transitions from low mass precursor ions. Pesticide names (and those of some metabolites) are supplemented by the molecular mass and the CAS number (Chemical Abstracts Service), which is useful for searches in databases. The CAS number is usually taken from 1, but in various cases mo
28、re than one number exists, e.g. for isomers and racemates. PD CEN/TR 16699:2014 CEN/TR 16699:2014 (E) 6 In addition to the above mentioned parameters, an indication on the appropriate collision energy for each transition is given. Instead of definitive voltages, a classification into low, medium and
29、 high collision energies was chosen, because transitions are based on data from different instruments, which do not require identical voltages to obtain the optimal intensity for a given transition. Therefore, from each reference (application note, article, etc.) all parameter sets were sorted by th
30、e collision energy in order to obtain the categories. Afterwards, the sorted list was divided in three groups of equal size. The resulting meaning of low, medium and high collision energy is listed in Table 1. Table 1 Categories of collision energy (CE) Instrument Voltage corresponding to low CE V V
