ProteomicsUltra high resolution linear ion trap Orbitrap mass spectrometer (Orbitrap Elite) facilitates top down LC MS/MS and versatile peptide fragmentation modes
Although only a few years old, the combination of a linear ion trap with an Orbitrap analyzer has become one of the standard mass spectrometers to characterize proteins and proteomes. Here we describe a novel version of this instrument family, the Orbitrap Elite, which is improved in three main area...

ProteomicsData-independent Acquisition for the orbitrap. A tutorial.
Data-independent acquisition (DIA) is a powerful mass spectrometric technique to perform both protein identification and quantification of complex protein samples. Setting up DIA methods on Orbitrap analyzers requires a thorough overview over the actions the Orbitrap mass spectrometers carry out. Th...

ProteomicsOptimizing chromatographic conditions for orbitrap-based MS platforms
We compared the performance of multidimensional protein identification (MudPIT) on Velos Pro Orbitrap (VPO) and Velos Orbitrap Elite (VOE) mass spectrometers to single dimension reversed phase (RP) chromatography on a Q Exactive Plus (QE+) and an Orbitrap Fusion™ Lumos™ (OFL). Using a digested HeLa...
