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 sample analysis that requires the ultrahigh resolution and high mass accuracy of FT-ICR. Currently active research areas include biological, 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.

    Pavement Sealant Leaches Environmental Contaminants

    New research shows that high concentrations of polycyclic aromatic hydrocarbons (PAHs) found in coal tar pavement sealants are oxidized into toxic, water-soluble compounds by sunlight and subsequently washed into the environment by rainwater, polluting natural water systems, negatively impacting marine ecosystems and public health.
