In mass spectrometry-based lipidomics, complex lipid mixtures undergo chromatographic separation, ionization, and detection using a high resolution, accurate mass (HRAM) instrument to simultaneously quantify and structurally characterize eluting species. The reported structural variety of identified lipids is strongly reliant on the analytical techniques utilized.

In this webinar we describe a novel lipidomics Real-Time Library Search (RTLS) approach on the Orbitrap Ascend™ Tribrid mass spectrometer which utilizes the lipid class of real-time identifications to trigger class-targeted MSn and to improve the structural characterization of glycerophospholipids and sphingomyelins in positive ion mode. Our class based RTLS method demonstrates improved selectivity compared to current methodology, enhancing lipid characterization applications.
