pressure mixing pump. The LC system was connected to a Q Exactive Focus hybrid quadrupole-Orbitrap mass spectrometer. Heated electrospray ionization (HESI) with positive-negative polarity switching was used. Detection was performed with a resolution of 35,000 (FWHM) @ m/z 200 in Full MS mode covering an m/z range between 100 and 600.

Thermo Scientific hybrid quadrupole-Orbitrap mass spectrometers enable both targeted and non-targeted screening and characterization. They also work with a broad range of sample type applications so that your laboratory can go from compound discovery to quantitation without relying on different instruments and technologies.

Orbitrap-based mass spectrometers are used in proteomics and are also used in life science mass spectrometry such as metabolism, metabolomics, environmental, food and safety analysis. Most of them are interfaced to liquid chromatography separations, though they are also used with gas chromatography and ambient ionization methods. Excel at the most challenging of applications, including low level PTM analysis, multiplexed relative quantitation using isobaric tags, intact protein characterization, as well as MSn analysis of small molecules with the new Thermo Scientific Orbitrap Fusion Lumos Tribrid Mass Spectrometer. Science-based website focusing on Orbitrap mass spectrometers with workflows for proteomics, metabolomics, lipidomics, pharmaceuticals, biopharmaceuticals, clinical, drugs of abuse, sports doping, environmental, and food safety for life science and analytical researchers. 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 .

The Orbitrap is an ion trap mass analyzer that consists of two outer electrodes and a central electrode, which enable it to act as both an analyzer and detector. Ions entering the Orbitrap are captured through "electrodynamic squeezing," after which they oscillate around the central electrode and in between the two outer electrodes. LC-MSn Orbitrap-based mass spectrometry Introduction Annotation of hundreds of unknown metabolites from human plasma is one of the most difficult challenges faced by metabolomics scientists.1 The degree of difficulty in the identification of unknown metabolites, however, depends on the information that can be extracted from an LC-MS dataset.
