Microflow liquid chromatography tandem mass spectrometry (μLC–MS/MS) is becoming a viable alternative to nanoflow LC–MS/MS for the analysis of proteomes. We have recently demonstrated the potential of such a system operating with a 1 mm i.d. × 150 mm column and at a flow rate of 50 μL/min for high-throughput applications. On the basis of the analysis of ∼38 000 samples measured on two

Orbitrap Velos Pro MS is a state of the art instrument for determination of molecular masses, elemental composition, and chemical structures of

These detectors are based on the confinement of ions in an electrostatic potential. The schematic representation of LC-HRMS with Orbitrap-MS is given 2020-12-29 · when used for LC-MS analyses. After method transfer, the Orbitrap Exploris 480 MS has become the primary system for lead selection studies. For each lead selection study, hundreds of samples are analyzed now with the Orbitrap Exploris 480 MS, and for each, a system suitability test antibody is analyzed several times. 2017-4-22 · LC/MS Analysis of the Monoclonal Antibody Rituximab Using the Q Exactive Benchtop Orbitrap Mass Spectrometer Martin Samonig 1,2, Christian Huber and Kai Scheffler2,3 1Division of Chemistry and Bioanalytics, University of Salzburg, Salzburg, Austria 2Christian Doppler Laboratory for Innovative Tools for Biosimilar Characterization, University of Salzburg, Salzburg, Austria Orbitrap Elite: Thermo Scientific Orbitrap Elite Mass spectrometer has a dual pressure linear ion trap coupled with high-field Orbitrap Mass analyzer facilitating increased sensitivity, reliability and dynamic range for better detection and MS n identification.

Supplementary Figures and Tables: Table S2: Feature comparison for spectral libraries. Optimization of LC-Orbitrap-MS conditions In the chromatographic separation, formic acid was added into mobile phase to protonate antibiotics between mobile phase composition and MS response for selected xx antibiotics. Regarding the organic solvent, acetonitrile showed better sensitivity (S/N) and peak shape than methanol. 2016-05-30 · Quantitative LC–MS performance of a new and affordable Q-orbitrap HRMS has been tested with 18 compounds in HR-full scan or MS/MS acquisition. Sensitivity, dynamic range of calibration curves and mass accuracy were the main aspects studied.
