This page includes a list of the major instrumentation in the Department.
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.
(Gas Chromatograph - Mass Spectrometer)
This Thermo Scientific capillary gas chromatograph and quadrapole mass spectrometer allows the identification of organic compounds
in a complex mixture. It is also extremely sensitive, routinely able to detect picogram quantities of many compounds.
(Nuclear Magnetic Resonance Spectrometer)
The Nuclear Magnetic Resonance Spectrometer is a Bruker 400 MHz multi-nuclear-probe instrument.
This instrument is fully automated and can be operated from anywhere in the world.
Students and faculty use NMR to determine structures of
organic and inorganic molecules. An NMR is the instrument from which medical Magnetic
Resonance Imaging (MRI) was developed.
(Fourier Transform Infrared Spectrometers)
The Nicolet 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 spectrometer resides in our introductory organic-chemistry laboratory.
The Nicolet spectrometer can produce spectra in the mid-IR and far-IR spectral ranges, and resides in the instrumentation laboratory.
The Cary 50 and Cary 300 Ultraviolet-Visible Spectrophotometers are 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.
The Hewlett-Packard 8452A diode-array UV-visible spectrophotometer can 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.
The PTI (Photon Technology International) Scanning Spectrofluorometer can observe luminescence in the form of fluorescence or phosphorescence.
Fluorescence is often accomplished at room temperature, while phosphorescence measurements are usually accomplished at liquid-nitrogen temperatures in
a dewar flask with quartz optics. Lifetime values can also be measured in either mode.
(High Performance Liquid Chromatograph)
The 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 spectrofluorometers.
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.
The Mettler/Toledo Differential Scanning Calorimeter (DSC) is very effective in measuring the thermal properties of solids, both organic and inorganic
compounds. Phase transitions are easily monitored as a function of changing chemical compostion and/or atomic structure.
The Mettler/Toledo Automated Titration unit can deliver small volumes of liquid in an almost endless array of possible situations. The
unit is linked to any combination of electrodes and the software can be used to produce the simplest of titrations to the most involved
arrangement of solution delivery and potentiometric analysis. The kinetics of reactions can be observed by using the system as a pH or voltage stat.
The Bio-Analytical Systems Electrochemical instrument provides a wide range of electrochemical techniques from standard voltammetric techniques
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.
The Perkin Elmer 460 Atomic Absorption (AA) Spectrophotometer can easily 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.
This Vacuum Atmospheres glovebox is an airproof compartment filled with an inert gas which allows
reactions to be accomplished without the presence of oxygen or water.
