Lipidomics Analysis—Thermo Q Exactive Orbitrap Mass Spectrometer

Summary

This is a high-resolution, accurate mass spectrometer with state-of-the-art Orbitrap mass detector. Separation is done either by Ultra High Performance Liquid Chromatography (UPLC) or by nano-HPLC prior to injection into the mass analyzer. Alternatively, some research groups use mass spectrometers like this for "shotgun" analysis of all compounds present, with no prior HPLC separation. The Q Exactive is available for lipidomic and other LC-MS/MS analysis on a case-by-case basis.
