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.

    Targeted annotation of peptides by selective infrared multiphoton dissociation mass spectrometry

    Protein oxidative damage is a common occurrence in a number of diseases, including cancer, neurodegenerative, and cardiovascular disease. Yet, little is known about its contribution to these illnesses. We developed a new technique, utilizing an infrared laser in combination with a mass spectrometer, to selectively identify sites of oxidation in complex protein mixtures. This sensitive and rapid platform may outperform current techniques and thus shed light on the involvement of oxidative damage in each of these diseases.
