Mark Schroeder1, Ioanna Ntai1, SiegrunMohring2, Markus Kellmann2, Alexander Harder2, Ralf Tautenhahn1, Amanda Souza1, and Andreas Huhmer1 ASMS 2020 Purpose: To develop robust metabolomics workflows using the new Thermo Scientific™ Orbitrap Exploris™ 240 mass spectrometer.
Methods: Chemical standards and complex biological matrices were analyzed with Thermo Scientific™ Vanquish™ UHPLC system and Orbitrap Exploris 240 MS. Data were processed using Thermo Scientific™ Compound Discoverer™ software and Thermo Scientific™ TraceFinder™ software.
Results: Robust reproducible measurements were achieved over multiple days with sub-ppm mass accuracy and signal response between 5 –10% CV. Confident elemental compositions were generated from accurate mass measurements and high-resolution settings while the AcquireX intelligent acquisition workflow resulted in more unique compounds with fragmentation spectra, thus delivering high quality data and versatility for all metabolomics workflows.
