Facilities

The Department of Chemistry and Biochemistry at Â鶹ӰԺ maintains outstanding research and instrumentation facilities to support the research mission of its faculty and students.  

Individual faculty laboratories are well equipped with chromatographic, spectroscopic, light-scattering, thermal analysis, gravimetric and mass-spectrometric equipment. Single-crystal and powder X-ray diffractometers are also housed in research laboratories in the department. Faculty members have custom-constructed unique Laser-Tweezers instruments and Fourier-transform microwave spectrometers, and a Surface Plasmon Resonance instrument has been installed. Â鶹ӰԺ State researchers have access to a wide array of synthetic techniques including photochemical, Schlenk-line and other air-sensitive methodologies. You can learn more about faculty research interests by browsing through our faculty directory.

Our students and faculty frequently collaborate with researchers in the Advanced Materials and Liquid Crystal Institute and other related departments. These collaborations may provide access to the Transmission Electron Microscope facility in the Advanced Materials and Liquid Crystal Institute and the Imaging Facility in Biological Sciences.

The Proteomics Core Facility assists researchers with isolation/purification, fractionation and DNA sequencing. Research Engineer Taylor Kurrle maintains the Department’s Glassblowing and Electronic shops in the basement of Williams Hall. The Physics/Chemistry machine shop in nearby Smith Hall provides expert machining services for our students and faculty.

Industrial researchers should contact Dr. Mahinda Gangoda, director of the department’s Analytical Instrumentation Facility, regarding pilot or short-term industrial research projects that may utilize the department’s research facilities.

Our Facilities

Analytical Instrumentation Facility

The Analytical Instrumentation Facility (AIF) located in the Department of Chemistry and Biochemistry performs pilot or short-term industrial research projects using a wide range of state-of-the-art analytical instruments.

Over the past twenty years the AIF has provided a cost-effective means for solving analytical problems faced by the local industrial community.  Projects involving separations and surface chemistry, materials science, and coatings are major emphases, but the AIF can also serve a variety of other areas with its broad range of instrumentation.

Major methods of analysis use high resolution NMR spectroscopy for solids and liquid systems, mass spectroscopy using GC or electrospray HPLC, various thermal analyses as well as conventional infrared spectroscopy, chromatographic separations and elemental analysis (C, H, N, S).  Titration calorimetry and more sophisticated (surface) infrared analyses are also available.

Major Instrumentation

Beckman Coulter Biomek 2000 Laboratory Automation Workstation

Beckman Coulter Biomek 2000 Laboratory Automation Workstation

The Biomek 2000 is a robust and low-cost expandable laboratory robotics system designed to perform liquid transfer and measurement tasks. The Biomek 2000 is controlled by a PC using the Windows XP-based BioWorksâ„¢ Operating System, an easy-to-use software program that directs all instrument functions.

Beckman Coulter ProteomeLab PF2D

Beckman Coulter PF2DCompared to traditional fractionation techniques, advantages of the PF2D chromatographic approach include:

  • High loading capacity without band distortion
  • Improved detection of low-abundance species
  • Membrane or hydrophobic proteins detection
  • Enhanced reproducibility
  • Contamination-free liquid flow path
  • Automation

Subsequent mass spectrometry analysis is easily coupled to the final fraction collector for MALDI or SELDI analysis of intact proteins or tryptic digestion followed by MALDI or ESI and peptide fingerprint mapping.

Cary 300 Series II Spectrophotometer

Cary 300 Series II Spectrophotometer

  • Pre-monochromator - Extends the working range of the Cary 300 past 5 absorbance units by lowering the stray light.
  • Sealed optics - prevents exposure to corrosive environments.
  • Variable slits - allow optimum control over data resolution. The spectral bandwidth can be set to 0.2 nm.
  • Phase locked wavelength drive - prevents peak shifts and peak suppression at high scan speeds.
  • Double choppers - ensure that the sample and reference beam strike the detector at the same point.
  • The large sample compartment - gives you more flexibility in sample size.
  • Centralized accessory control - all accessories are centrally controlled by the Accessory Controller.
