Abstract: Most mass analysis relies on “nominal” mass accuracy (i.e., to within 1 Da). However, more and more applications are based on much more accurate mass measurement. High mass resolving power (m/Δm50% > 500,000 over a wide mass range) offers two major advantages. First, it becomes possible to separate complex mixtures without prior chromatographic or gel separation. Second, elemental composition may be determined from accurate (to ~100 ppb) mass measurement alone for unknown molecules up to ~1,000 Da. Examples include protein post-translational modifications and site-specific redox potentials, lipidomics, metabolomics, and mapping contact surfaces in protein assemblies for drug targets. Fourier transform ion cyclotron resonance mass spectrometry offers 10-100x higher mass resolution than other mass analyzers. [Supported by NSF DMR-11-57490 and the State of Florida.]
