Overview

 

The identification of metabolites detected in untargeted UHPLC-MS metabolomics studies can be a significant hurdle and is essential to derive biological knowledge from data. Chromatographic retention time, full-scan accurate m/z and MSn data can all be used, in combination with chemical standards and in-silico workflows where available, to identify metabolites.

The first part of the webinar will discuss the current processes applied to identify metabolites applying UHPLC-MS platforms including the current strengths and limitations and the progress made in increasing identification success and accuracy.

The second part of the webinar will showcase advances with high resolution accurate mass (HRAM) mass spectrometry instrumentation and software so to deliver complementary information with multiple dissociation techniques and robust MSn data in a routinely applied workflow so to maximize the number of metabolite annotations. New intelligent data acquisition strategies to collect more informative MS and MSn data that maximizes metabolome coverage and increase confidence in the identification of metabolites will be presented.
