Thermo Scientific Orbitrap Fusion Tribrid Mass Spectrometer Unmatched analytical performance, revolutionary MS architecture • Tribrid architecture combines quadrupole, linear ion trap, and Orbitrap mass analyzers • Multiple fragmentation techniques—CID, HCD, and optional ETD and EThCD—are available at any stage of MSn, with Orbitrap quantitation: lab of the future Close your uncertainty gap with the selectivity and confidence of HRAM Table of Contents Introduction (LC-QQQ MS) technology has been the standard for quantitation of many types of compounds, from pesticide residues in food and feed, to testosterone in plasma and urine for research applications. 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. New LC-LTQ-Orbitrap method compared with old LC-MS/MS method. Honey samples were spiked with an internal standard solution consisting of seven antimicrobial compounds, two of which were deuterated and two labelled with 13C. The honey was taken up in water and acidified methanol was added.

The use of ultra-high pressure LC (U-HPLC) in combination with the Orbitrap detection, both for peptide and small molecule analyses is of a particular interest.

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.
