• Demonstrate the utility of LC/MS and data-dependent MSn acquisition for simultaneous lipid profiling and more complete lipid annotation using the Thermo Scientific™ Orbitrap™ ID-X™ Tribrid™ mass spectrometer and Thermo Scientific™ LipidSearch™ software. • Show that the use of the Thermo Scientific™ AcquireX intelligent acquisition method combined with neutral loss and product ion scan filters increases the overall quality and number of lipid annotations. • Investigate the utility of combining HCD MS2 and CID MSn for structural determination of phosphatidylcholine and triglyceride species in lipid extracts from insect larvae.
