This page includes a list of the major instrumentation in the Department.
Biology/Chemistry Building
The Biology/Chemistry Building contains the entire Department of Chemistry
plus the Department of Biology and the Environmental-Engineering Laboaratory.
The Department of Chemistry moved to this new facility in the summer of 2005
and is housed on the 2th floor.

Instrumentation is fundamentally important to both teaching and research in the
department. Students are encouraged to become experienced users with all the
instruments, both in laboratory classes as well as in chemical research. As the
variety of instruments available continues to grow, we will be able to look at
even more varied and intriguing chemical systems. After adding a powerful new Agilent HPLC system this last year (see below), we are currently in the process of evaluating molecular spectrometers and calorimetry equipment for the 2004-2005 academic year.
(Gas Chromatograph - Mass Spectrometer)
This
instrument allows us to identify very accurately which organic compounds are
present in a complex mixture. It is also extremely sensitive, able to detect
part-per-million quantities of many compounds.
(Nuclear Magnetic Resonance Spectrometer)
The Nuclear Magnetic Resonance Spectrometer is a Bruker 200 MHz multi-nuclear
probe instrument. The department uses NMR to determine precise structures of
organic and inorganic molecules. An NMR is the instrument from which medical Magnetic
Resonance Imaging (MRI) was developed.
(Fourier-Transform Infra-Red Spectrometers)
The Mattson FTIR (left) and Bruker FTIR (right) allow us to identify chemical functional
groups in a compound caused by bond vibrations. The FTIR instruments can collect many
spectra very rapidly over the entire infrared spectrum The Bruker instrument resides in our introductory organic-chemistry laboratory.
The Cary 50 and Cary 300 Ultraviolet-Visible Spectrophotometers is able to record spectra from deep in the ultraviolet region of the electromagnetic spectrum through the visible region and into the near infrared. The award-winning Cary 50 is a rapid-scanning spectrometer ranging from 190nm to 1100nm. The Cary 300 gives us the increased stability and sensitivity, and is used for routine measurements, moderately rapid kinetic measurements, and for long-term kinetic studies.
(High Performance Liquid Chromatograph)
Our new Agilent High Performance Liquid Chromatograph allows us to analyse the
composition of a liquid sample. The on-board Diode Array spectrometer gives the instrument incredible versatility. There is also an active interface that allows us to use some of the more common detectors such as other Ultraviolet-Visible spectrophotometric devices, conductivity and refractive-index detectors, and flourescence.
(Capillary Electrophoresis)
This exciting new instrumental method is expanding rapidly as a prime means of separation and detection of everything from small molecules to small cells. Virtually unknown two decades ago, this technique is rapidly becoming the method of choice for the analysis of "difficult" samples.
Our Bio-Analytical Systems Electrochemical instrument provides a wide range of electrochemical techniques from polaragraphy to sophisticated time-dependent voltammetry. Thus, the instrument can be used for routine analysis of electrochemically-active species as well as for investigations of complex redox reactions.
Hewlett-Packard 8452A diode-array UV-visible spectrophotometer allow us to record whole ultraviolet and visible spectra at each instrument reading. This monitoring of multiple wavelengths simulataneously facilitates multiple-component analysis. We often use this instruments to help us unravel complex reaction processes and their kinetics in solution.
Perkin Elmer 460 Spectrophotometer. This instrument can detect
part-per-million quantities of metal ions in solutions. AA as the technique is
called is often used to measure metal ion pollution, such as lead,
in drinking water.
Vacuum Atmospheres glovebox. An airproof compartment filled with an inert gas allows
reactions to be carried out without the presence of oxygen or water.
