The increasing concern around trace-level food and environmental pollutants is driving the demand for more rapid and reliable methods for the identification of chemical residues. Meeting this challenge not only requires the fast deployment of technologies that can differentiate pesticides, PAHs, and other targets from organic interferences, but also requires the complex task of the analyst to search for hundreds of compounds in a wide variety of crop and environmental matrices. This presentation will discuss the application of three different GC/MS platforms for pesticide analysis in a selection of thirty different brands of strawberries – the number one fruit in the Environment Work Group “Dirty Dozen” list for the last three years.<br/>GC/MSD analysis utilized streamlined data processing with the Agilent’s MassHunter SureTarget automated deconvolution and library searching software. GC/MS/MS analysis employed targeting screening for trace level detection with the use of Agilent’s Pesticide and Environmental Pollutant MRM Database for over 1100 components. GC/Q-TOF non-targeted screening incorporated the use of a curated accurate mass database for analyte discovery.<br/>The benefits of each approach will be discussed in achieving high quality screening with confident quantitative capability.
