FT-ICR MS offers the highest broadband mass resolution and mass accuracy. FT-ICR mass resolving power varies directly with applied magnetic field strength (NHMFL’s 21 tesla offers the world’s highest field for ICR). FT-ICR MS is uniquely advantageous for resolution and assignment of elemental compositions for complex mixtures, ranging from petroleum crude oil (>125,000 assigned peaks in a single mass spectrum) to top-down proteomics. Benchmark performance will be illustrated for applications ranging from environmental oil spills to diagnostic identification of proteoforms in multiple myeloma and hemoglobinopathies. [Work performed at the National High Magnetic Field Laboratory, supported by NSF Division of Chemistry through DMR-1157490 and DMR-1644779 and the State of Florida.]



Alan G. Marshall completed his B.A. degree with Honors in Chemistry at Northwestern U. in 1965, and his Ph.D. in Physical Chemistry from Stanford U. in 1970. He joined the Chemistry faculty at the University of British Columbia (Vancouver, Canada) in 1969. He moved to Ohio State University in 1980 as Professor of Chemistry and Biochemistry and Director of the Campus Chemical Instrument Center. In 1993, he moved to Florida State University, where he is Robert O. Lawton Professor of Chemistry and Biochemistry and Founding Director and Chief Scientist of the Ion Cyclotron Resonance (ICR) Program, a National Science Foundation user facility for mass spectrometry.

He co-invented and leads the continuing development of Fourier transform ICR mass spectrometry. His current research spans FT-ICR instrumentation development, fossil fuels and environmental analysis, and mapping the primary and higher-order structures of biological macromolecules and their complexes.
