Features: Novel high-field Orbitrap analyzer; Resolving power > 240,000 FWHM MS results in higher number of precursor ions triggered for MS/MS—synonymous with improved productivity. Analyze complex mixtures faster than ever!

The Orbitrap differs from FTICR-MS by the absence of a magnetic field and hence has a significantly slower decrease of resolving power with increasing m/z. Supplementary Methods: Table S1: LC-MS parameters for six protocols used for generating EMBL-MCF spectral library. Other LC parameters: Q-Exactive Orbitrap mass spec parameters. Data analysis for online upload and curation of the LC-MS/MS data sets. Supplementary Figures and Tables: Table S2: Feature comparison for spectral libraries.

• TMSCHN 2 pre-methylation enhanced MS intensity by 2–3 orders of magnitude.. SPE is required for authentic samples containing trace phosphonates (at ng/L level). 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.
