Mass Spectrometry Facility

The Department of Chemistry and Biochemistry operates an in-house Mass Spectrometry facility to support research and teaching activities. Mass Spectrometry is a primary tool for structure elucidation, molecular weight determination and molecular formula confirmation for organic and biological materials. This family of techniques measures the masses of organic and biological molecules by creating gas phase ions from the analytes and manipulating those ions in electric and magnetic fields. Chemical structure may be probed by fragmenting molecular ions and mass measuring the resulting product ions. 
 
Ionization Techniques Available:
Electron Ionization (EI)
Chemical Ionization (CI)
Field Ionization/Field Desorption (FI/FD)

Instruments

  1. High Resolution Time-of-Flight mass spectrometer

    This high resolution Time-of-Flight mass spectrometer is primarily used for small organic analytes and low polarity materials.

  2. HP 5970 GC/MS

    An HP 5970 GC/MS running in dedicated EI mode (mass range < m/z 550) is available for open access usage. The instrument is equipped with a J&W DB-5ms 30m GC column, with 0.25 mm ID and 0.25 µm film thickness.

  3. MALDI TOF Mass Spectrometer

    This MALDI TOF mass spectrometer is used for the analysis of a broad range of compounds including small molecules, peptides, proteins, nucleic acids, and synthetic polymers.
