Parameters for the determination of pesticide residues

More than 800 pesticides are being used world-wide. However, residues of a large number of these pesticides can up to date only be analysed using costly methods. A new promising tool for the determination of residues of such pesticides is liquid chromatography combined with tandem mass spectrometry. Multiple Reaction Monitoring (MRM) is the preferred scan type for this kind of application.

MRM requires individual parameters for each compound to be analysed. On our website such parameters are offered, all of which have been obtained in our own laboratories. A list of all pesticides included so far is available for download in the “Documents” section at the bottom of this page. Currently, the list includes 482 pesticides.

Complete acquisition parameter sets using an API 2000 mass spectrometer (Applied Biosystems) in combination with single quad mass spectra and product ion scans are provided in the archives "Complete acquisition parameter sets for positive electrospray" (size approx. 52MB) and "Complete acquisition parameter sets for negative electrospray" (size approx. 5MB) which can be downloaded from this page. An example for the kind of data to be found in this archive is provided in the file "Example from the acquisition parameter sets for API 2000 mass spectrometers".

Tuning of other types of instruments or the confirmation of positive findings may be supported by product ion spectra. For 541 pesticides such spectra are offered in the additional archive "Library of product ion spectra for pesticide residue analysis" (size approx. 47 MB). An example for these mass spectra can be found in the file "Example for product ion spectra for pesticide residue analysis".

Application of the parameters in a multi residue method for the determination of pesticides in drinking water

For 300 pesticides listed in the overview a complete multi residue method was developed using an API 4000 mass spectrometer. A lot of pesticides can be analysed at concentrations of 0.1 µg/l by this method. The complete results of the method development are provided in the archive „Fast multi residue screening of 300 pesticides in drinking water“ (size approx. 28MB) at the bottom of this page.


Alternatively to the download of all files, BfR offers a CD ROM free of charge containing all information provided in the aforementioned archives. If you are interested in such a CD ROM please send an e-mail with your complete address to pressestelle@bfr.bund.de.

Periodically, new information will be added to this site. Please note that the absence of errors cannot be guaranteed. We do appreciate any comment to improve this compilation. Your contact person at BfR is Dr. Lutz Alder, e-mails can be sent to: lutz.alder@bfr.bund.de.
