The traditional approach to monitoring organic contaminants involves analyzing a defined number of target compounds by mass spectrometry with the instrument operated in a selected data acquisition mode for targeted analytes. However, there is evidence that such an approach may significantly underestimate the exposure and risk of pollutants, compared to a more comprehensive broad-scope targeted and untargeted screen. Recent advances in mass spectrometry allows an increased scope of analysis when using high resolution accurate mass instruments operated in full spectrum acquisition mode. Accurate mass information enhances the amount of detail in the information collected and allows for the determination of both targeted and non-targeted components. This study will present a workflow combining targeted quantitation, a broad-scope as well as non-targeted screening using surface water samples collected in Sacramento-San Joaquin Delta in Northern California.
