Division/Committee: [ENVR] Division of Environmental Chemistry

Recent advances in analytical instrumentation (i.e. GC/LC-HRMS) and data processing approaches have paved the path to the discovery of a growing number of chemicals of interest (e.g. of biological relevance) in complex samples. However, the non-targeted analysis (NTA) experiments are extremely challenging to set up and may require specifically developed tools/approaches, depending on the initial hypothesis. In this session we aim at discussing the existing tools from the experimental setup to data processing approaches for the NTA experiments when dealing with complex samples. The experimental strategies will include novel HRMS, ion mobilty spectrometry (IMS), nuclear magnetic resonance (NMR), and chromatographic approaches (e.g. LCxLC). Discussion on the data processing tools will cover the latest developments related to the steps taken during the NTA experiments from the feature detection to the identification of unknown unknowns, as well as quantitative NTA. This session will provide a forum for discussing the state of the arts in NTA and the needed future developments from the experimental setup to the digital approaches. This symposium will give the developers (i.e. both experimental and digital) the means to present their research while the application oriented researchers will be able to discuss their future needs and desires.
