Essential Lipidomics Experiments Using the LTQ Orbitrap Hybrid Mass Spectrometer

Instrument Type: LCMSMS

We tested the performance of a novel mass spectrometer, the Thermo Scientific LTQ Orbitrap, in a multitude of different applications in the field of lipidomics. The experiments presented here take advantage of the LTQ Orbitrap capabilities of multiple stage fragmentation, high resolution and mass accuracy to solve challenges of quantitating isomeric glycerophospholipids, resolving isobaric species, and elucidating fragmentation pathways and compositional assignment of various lipid species.

Comparative analysis of cooking oils using a solid core HPLC column

Instrument Type: HPLC-CAD

The use of Thermo Scientific Accucore C30 HPLC columns for the characterization of different cooking oils is demonstrated. The C30 phase offers greater selectivity and resolution of minor components when compared to the C18 phase.
