column, at a flow rate of 1 μL/min Mass Spectrometry The Q Exactive benchtop Orbitrap mass spectrometer was used for all experiments in this study. Experiments using the ProSwift RP-10R 50 mm x 1 mm i.d. column 2018-08-01 · LC-Orbitrap MS and LC-TOF MS produce similar data in full scan acquisition mode. In addition, although LC-Orbitrap MS has a higher mass resolving power, both analyzers provide comparable mass accuracy (Gómez-Pérez, Romero-González, Vidal, & Frenich, 2015b). LC-quadrupole/Orbitrap high-resolution mass spectrometry enables stable isotope-resolved simultaneous quantification and 13 C-isotopic labeling of acyl-coenzyme A thioesters Alexander J. Frey 1 Daniel R. Feldman 1 In parallel, an LC-Orbitrap MS platform was used to verify the efficiency of the method as well as a tool to increase the identification confidence of the proposed markers. Based on the results, with FIA-MRMS, comparable and improved projection and prediction models were generated in comparison to those of the more established LC-MS methodology.

Metabolomics technologies are increasingly used to study metabo Workflow Overview for Glycan Identification and Characterization The attractive feature of mass spectrometry based methods, compared to other techniques for glycan analysis, is the maximization of structural information relative to the amount of time, labor and sample quantity. Q-exactive Mass spectrometer LC-Orbitrap-HRMS was also found to be increasingly important for the analysis of bioactive substances, principally phenolic compounds in foods. A number of studies reported for the first time the identification of new fungal metabolites, predominantly various conjugated forms of known mycotoxins.
