Facilities & Instrumentation

Upham Hall has just undergone a $40-million renovation and is now one of the University’s premier learning facilities. This building, completed in Fall 2006, houses new research laboratories and faculty offices and features four 60-seat classrooms, one 108-seat lecture hall, one 185-seat lecture hall, well equipped multimedia classrooms, modern research laboratories, a second floor consisting mostly of chemistry labs with new fume hoods and demonstration benches, and 34,000 square feet of new space. The small size of the chemistry department allows students direct, hands-on access to all department instrumentation, including:

  • 300 MHZ nuclear magnetic resonance spectrometer (NMR)
  • EMX-plus electron spin resonance spectrometer (ESR)
  • Electrochemical analyzer
  • Fluorescence spectrophotometer
  • Fourier Transform-IR spectrophotometer (FTIR)
  • Gas chromatograph-mass spectrometer (GC-MS)
  • High-performance liquid chromatograph (HPLC)
  • Ultraviolet-visible spectrophotometer (UV-Vis)
  • Atomic absorption spectrometer (AAS)
  • Gas chromatograph (GC)
  • Inductively coupled plasma spectrometer (ICP)
  • Differential scanning calorimeter (DSC)

Instrumentation Summary:

The Department has the following state of the art instruments: a nuclear magnetic resonance spectrometer (NMR) an electron spin resonance spectrometer (ESR), a Fourier Transform-infrared spectrometer (FTIR), a diode array UV-Visible spectrophotometer and a fluorescence spectrophotometer, which are used to probe the nature of molecules prepared by students in various chemistry student laboratories. Additionally, the department also has an atomic absorption spectrometer and an inductively coupled plasma spectrometer (ICP) which can be used to determine the concentrations of most elements in up to ppm or ppb levels.

Furthermore, the department also possesses a gas chromatograph (GC) and a high-performance liquid chromatograph (HPLC), which are used to separate and characterize chemicals in complex mixtures. The gas chromatograph-mass spectrometer (GCMS) housed in the department is composed of two major building blocks: a gas chromatograph and a mass spectrometer. These two components, used together, allow a much finer degree of substance identification than either unit used separately.

The department is capable of conducting thermal analysis as well using its sophisticated differential scanning calorimeter (DSC), which can be used to measure a number of characteristic thermal properties of a sample.

All these instruments are coupled with computers that allow sophisticated data acquisition and manipulation.

Finally, the department has a number of minor instruments or equipment: an electrochemical analyzer to study the electrochemical and spectroelectrochemical properties of a compound, parallel reactors to carry out many reactions at a very fast pace; a polarimeter to measure optical rotation of optically active matter, a tube furnace to conduct syntheses and purifications of inorganic compounds, a bomb calorimeter to measure the heat of chemical reactions or physical changes as well as heat capacity and a magnetic balance to measure magnetic susceptibility.
