The Thermo Scientific CTC HTS PAL autosampler was kept at 10 °C, the injection volume was 5 μL. Online sample extraction was performed on a mixed-phase properties Cyclone MCX-2 (0.5 x 50 mm) column from Thermo Scientific. 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. 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. Analysis of trace phosphonates in authentic water samples by pre-methylation and LC-Orbitrap MS/MS Water Res .

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.
