Lowering Detection Limits for Routine Analysis of Pesticides Residues in Foods Using the Agilent 7000C Triple Quadrupole GC/MS

Version 1

    Application Note

    Food Safety



    An analytical method that is well established for the Agilent 7000 Series Triple Quadrupole GC/MS has been employed to demonstrate performance of the 7000C Triple Quadrupole GC/MS. When 110 pesticides were spiked into plum and winter squash matrix at a concentration of 1 ng/g, calculated %RSDs were ~ 20 (n = 5) for 92 pesticides analyzed in difficult plum matrix and for 92 of the pesticides in winter squash as well. It was estimated that limits of quantitation (LOQ) ~ 5 ng/g could be reached for 91% of the pesticides studied in either commodity. Thus, it was demonstrated that data collection at levels below the threshold MRL in the EU and in Japan, 0.01 mg/kg (10 ng/g), is achievable to monitor exposure.
