FT-ICR
Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR), also known as Fourier transform mass spectrometry (FT-MS), is a type of mass analyzer (or mass spectrometer) for determining the mass-to-charge ratio (m/z) of ions based on the cyclotron frequency of the ions in a fixed magnetic field.
The University of Warwick Ion Cyclotron Resonance (FT-ICR) Laboratory houses a Bruker 12 T solariX FTICR mass spectrometer with the capabilities outlined below, and in Summer 2021 we will be taking delivery of a new Bruker 15 T solariX 2xR instrument.
Example research areas include: peptides and proteins (e.g. post-translational modifications, deamidation and isomerization of aspartic acid residues), ionization methods, petroleum (crude oils, asphaltenes, etc.), fuels, bio-oils/biofuels, environmental samples, agrochemicals, and development of new data processing methods.
To arrange use of the facility, please contact Prof. Peter O'Connor (p.oconnor@warwick.ac.uk) and Dr. Mark Barrow (M.P.Barrow@warwick.ac.uk) in the first instance to discuss your needs prior to submitting your application.
