The SCIEX iMethod™ Pesticide LC-MS/MS Library Version 1.1 contains information on 636 common pesticides and their metabolites that are required to be monitored in vegetables or other food products. The multiple reaction monitoring (MRM) catalogue contains up to three transitions per compound. Each compound in the library has individual spectra acquired using three distinct collision energies (20 eV, 35 eV, 50 eV), as well as a single spectra representing the sum of all three collision energies. If compounds ionize in both polarities, spectra for both are also included, bringing the total number of spectra per compound to eight.
Use stand-alone to create custom screening and/or quantification methods
The MRM catalogue can be used to build methods without the need to re-infuse standards and optimize MRM transitions for a given compound. Screening and quantitation methods can be created for use with an MRM-triggered enhanced product ion (EPI) workflow and a QTRAP® System; additionally, traditional quantitation can be completed using the response ratio for two or more transitions for compound confirmation. The latter approach can be performed on either an API Triple Quad™ System or a QTRAP® Series instrument. Users simply select the compounds of interest as well as the number of transitions to be monitored from the MRM catalogue. Once selected, the Cliquid® Software automatically creates the acquisition and processing methods.
