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.

    Sunlight converts plastics into diverse chemical mixtures

    Sunlight can chemically transform plastics from consumer plastic bags into complex chemical mixtures that leach into the ocean. Understanding the impact of plastic pollution requires advanced analytical techniques that can identify transformed plastic molecules in water samples, and requires instrumentation only available at the Maglab.
