Mass Spectrometry Facility

Pat Limbach

Our facility is dedicated to inorganic, organic and biological mass spectrometry analyses. Our facility is one of the two primary centers for the State of Ohio Mass Spectrometry Consortium. Participating universities in this Consortium are the Ohio State Center, the Cincinnati Center, Akron, Toledo, Ohio University, Miami, Kent, Youngstown, as well as many other Ohio universities, clinics, and industrial laboratories. The University of Cincinnati Facility will not only provide access to the instruments at the Cincinnati Facility, but also all instruments at other participating universities. The Consortium is working to establish network links to allow rapid data transmission between various sites.
Technical direction for the facility is provided by the Faculty Supervisor, Chemistry Professor Pat Limbach. Our staff, Dr.Stephen Macha and Dr. Larry Sallans maintain day-to-day operations in the facility. New users are invited to contact them to discuss your analysis needs at (513) 556-1575.

  • Thermo LTQ Linear Ion-Trap FTMS

    The Thermo LTQ-FT™ combines the most advanced Ion Trap and Fourier Transform Ion Cyclotron Resonance technologies into a single instrument with unprecedented analytical power and versatility. While the FT-ICR is providing high mass accuracy and high resolution mass spectra, the linear ion trap can simultaneously provide multiple collision-induced dissociations for structural identification. Extremely sensitive while possessing a mass accuracy of less than 1 ppm, mass resolution exceeding 100K, and MSn capabilities.

  • Micromass GCT-MS

    This is a compact, fully integrated, high performance, orthogonal acceleration time-of-flight (1.2 meters) GC-MS. The source options on this instrument include Electron Impact (EI), and Chemical Ionization (CI). It can provide full mass spectra with resolution up to ~7000 FWHM which allows good mass accuracy with a single internal reference mass. The instrument has NIST GC Compound Library search capabilities to facilitate the identification of unknowns.
