Table 1. LC gradients used for experiments with the PepSwift 250 mm x 0.2 mm i.d. 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).

2017-03-01 · Recent advances in LC-MS determination of polyphenols in food are presented. • Sample treatment, separation, ionization and MS detection are addressed. • HRMS relevant applications on polyphenols with Orbitrap and TOF are reviewed. • Chemometrics for optimization and characterization of polyphenols is discussed.

The pipeline setup includes an intelligent data acquisition with AcquireX™ linked to LC-Orbitrap Tribrid-HRMS (MS 3) and coupled to Compound Discoverer data processing. Twenty-eight unknown compounds were tentatively identified using very restrictive criteria that includes exact mass, isotopic profile, MS 2 match, retention time and MS 3 match.

Liquid chromatography–mass spectrometry (LC-MS)-based untargeted metabolomics studies require high-quality spectral libraries for reliable metabolite identification. We have constructed EMBL-MCF (European Molecular Biology Laboratory–Metabolomics Core Facility), an open LC-MS/MS spectral library that currently contains over 1600 fragmentation spectra from 435 authentic standards of Optimization of LC-Orbitrap-HRMS acquisition and MZmine 2 data processing for nontarget screening of environmental samples using design of experiments Anal Bioanal Chem . 2016 Nov;408(28):7905-7915. doi: 10.1007/s00216-016-9919-8.
