Multiresidue Pesticide Analysis with the Agilent Intuvo 9000 GC and Agilent 7000 Series Mass Spectrometer
This application note shows an evaluation of pesticides in seven different matrices for the Agilent Intuvo 9000 GC and an Agilent 7000 Series Mass Spectrometer.
Calibration curves for 21 pesticides showed excellent linearity for concentrations ranging from 1 ng/mL to 1,000 ng/mL. Excellent response and peak shape consistency was obtained with the implementation of the Agilent Intuvo Guard Chip, which protects downstream components and eliminates the need to trim the column after matrix evaluation. Average recovery for a 50 ng/mL sample across 60 food extract injections was over 80 %, with an RSD of less than 10 %. With regular maintenance, including liner and Intuvo Guard Chip replacements, peak shape and recoveries were found to be unchanged for over 500 injections.
