Application Note: Analysis of 446 Pesticides and 1202 Transitions in a Single Run on the Thermo Scientiﬁc TSQ Quantum XLS GC-MS/MS
24 Apr 2013
As more compounds are being added to governmental monitoring lists, screening methods for large numbers of compounds are becoming important to laboratories analyzing foods for pesticides. This application note describes an instrument method developed on the Thermo Scientiﬁc TSQ Quantum XLS triple quadrupole mass spectrometer to analyze 446 pesticides using 1202 transitions. A peak width of 0.7 Da was used to provide the selectivity needed to analyze this number of compounds in a 35 minute run. The use of the software’s EZ method feature allows the user to import all of the com- pound transition information from an Excel® spreadsheet.
