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.

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.

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.

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. High-resolution, accurate mass spectrometry based on Orbitrap™ technology for the first time offers an efficient and easy-to-use solution for the challenge at hand. The high resolution of up to 140,000 FWHM enables separation of drugs from interferences. Fast positive/negative switching catches acidic, basic and neutral drugs. Workflow Overview for Targeted Quantitation While targeted peptide quantitation has historically been the domain of triple-quadrupole mass spectrometers, recent advances in Thermo Scientific Orbitrap-based instruments have made them equally well-suited to quantitative experiments.
