Purpose: Demonstrate the benefit of Thermo Scientific™ FAIMS Pro™ interface for proteomic data-dependent experiments and establish an optimized method setup with the new Thermo Scientific™ Orbitrap Exploris™ 480 mass spectrometer. Methods: A commercially available tryptic HeLa digest was separated over different gradient lengths and subsequently analyzed in data-dependent acquisition mode on an Orbitrap Exploris 480 equipped with a FAIMS Pro interface. Results: The use of peptide gas-phase fractionation with the novel Orbitrap Exploris 480 and optimized method setup increases protein identification rate by up to 15% and can be achieved with both nano and capillary flow conditions.
