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.

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.

They were as follows: data-dependent MS2 (dd-MS2), all-ion fragmentation (AIF) and variable data-independent analysis (vDIA). These MS2 workflows were tested for the main method validation parameters such as detection and identification capabilities Q-exactive Mass spectrometer Take a tour of the new Thermo Scientific Orbitrap Exploris 240 LC-MS flying ions animation video.

Our Orbitrap-based MS systems connect to liquid chromatography instruments to enhance separation of unknown and known compounds and enable high-throughput workflows.

While analysis of denatured proteins may be the most common LC/MS protein analysis, many biopharmaceutical and biological research applications require 

Metabolomics is the comprehensive analysis of endogenous metabolites in biological specimens. 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.

Public Health 8:558226. doi: 10.3389/fpubh.2020.558226 2011-04-01 Furthermore, we found that the Orbitrap analyzer, rather than the analytical column, was easily saturated with higher loading amount, thus limited the dynamic range of MS1‐based quantification. By using optimized parameters, 10 000 proteins and 110 000 unique peptides were identified by using 20 h of effective liquid chromatography (LC) gradient time.
