This facility is charged with developing and exploiting the unique capabilities of Fourier Transform Ion Cyclotron Resonance (FT-ICR) mass spectrometry, and leads the world in instrument and technique development as well as novel applications of FT-ICR mass spectrometry.

The facility features directors for instrumentation, biological applications, environmental, petrochemical applications, and user services as well as a machinist, technician and numerous rotating postdocs who are available to collaborate and/or assist with projects.

The facility provides service operations for sample analysis that requires the ultrahigh resolution and high mass accuracy of FT-ICR. Research falls in the areas of biomolecular analysis, hydrogen-deuterium exchange and environmental and petrochemical analysis. The facility's four FT-ICR mass spectrometers feature high magnetic fields – including the world-record 21 tesla – and are compatible with multiple ionization and fragmentation techniques.


Our magnets are open to all scientists — for free — via a competitive process and we accept proposals throughout the year.

    MagLab FAIR Data Empowers 'Data Users'

    A new type of MagLab user has emerged: A Data User – who accesses MagLab data from repositories to advance individual research goals. In this highlight, the original work was a benchmark study on the performance of the 21T FT-ICR system that produced a set of data on colorectal cancer cells that has become a 'gold standard' for testing new data analysis algorithms and software packages. The original data set was later used in a poster and two papers in alignment with the MagLab's FAIR data initiative.
