Public LC-Orbitrap-MS/MS Spectral Library for Metabolite Identification [PDF]
, 2020 ABSTRACTLiquid chromatography-mass spectrometry(LC-MS)-based untargeted metabolomics studies require high-quality spectral libraries for reliable metabolite identification. We have constructed EMBL-MCF, an open LC-MS/MS spectral library that currently contains over 1600 fragmentation spectra from 435 authentic standards of endogenous metabolites and ...

Separation and quantification of imidazoles in atmospheric particles using LC–Orbitrap‐MS [PDF]
Journal of Separation Science, 2019 AbstractA method using ultra‐high performance liquid chromatography coupled to a high resolution Orbitrap mass spectrometer was developed to identify and quantify imidazoles in aqueous extracts of aerosol particles. The aqueous particle extract was used without further enrichment or sample clean‐up.

Improved LC−MS Method for the Determination of Fatty Acids in Red Blood Cells by LC−Orbitrap MS [PDF]
Analytical Chemistry, 2011 We report a new method for fast and sensitive analyses of biologically relevant fatty acids (FAs) in red blood cells (RBC) by liquid chromatography mass spectrometry (LC-MS). A new chemical derivatization approach was developed forming picolylamides from FAs in a quantitative reaction.

MS-H: a novel proteomic approach to isolate and type the E. coli H antigen using membrane filtration and liquid chromatography-tandem mass spectrometry (LC-MS/MS). [PDF]
PLoS ONE, 2013 Serotyping is the long-standing gold standard method to determine E. coli H antigens; however, this method requires a panel of H-antigen specific antibodies and often culture-based induction of the H-antigen flagellar motility. In this study, a rapid and
