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

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.

Mätning av accurate mass → med flera decimalers noggrannhet Ultra high resolution linear ion trap Orbitrap mass spectrometer (Orbitrap Elite) facilitates top down LC MS/MS and versatile peptide fragmentation modes. A mini‐symposium “Soft ionization methods and LC/MS” was arranged and particularly LTQ Orbitrap hybrid mass spectrometry, proteomics and DESI.

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.
