Multi-residue pesticide analysis is challenging due to the low limits of detection required in a diverse range of food commodities. As there are currently well over 1000 pesticides in use, laboratories are under increasing pressure to broaden the range of pesticides determined. In this technology brief, we demonstrate the ability to maintain mass accuracy on high concentration violations for compounds of interest in a screening experiment. This removes the risk of false negatives associated with the presence of high concentration pesticide violations in food and environmental samples.
