The Chemical Instrumentation Facility has over five million
dollars worth of analytical instrumentation available to faculty,
graduate students, industry, and other educational institutions.
The staff of five highly qualified professionals supports university
research by keeping the analytical equipment available and operable
and by providing application support and user training. Services
available to the research community include the following:
Magnetic Resonance
Eight NMR spectrometers of varying frequencies from 60 to 500
MHz are available. Magnetic Resonance spectroscopy allows the
use of atomic nuclei as magnetic probes within a molecule. Chemical
analysis and spatial orientation are determined by using this
technique. A fully equipped EPR system is also available. Equipment
located in the facility includes a Bruker DRX-400 NMR, Varian
VXR-300 and VXR-400 NMRs, a Bruker AC-200 NMR, a Bruker MSL-300
NMR, several 60 MHz teaching instruments, and a Bruker ER-200
EPR. A Bruker DMX-500 NMR is available in the Molecular Biology
Building.
Mass Spectrometry
The mass spectrometry lab is equipped to provide both low resolution
GC-MS on mixtures and high resolution measurements for determining
the elemental composition of pure samples. In addition, APCI,
electrospray, and MALDI are used for the ionization of higher
molecular weight compounds, particularly those of biological origin.
LC, CZE, and CIEF interfaces with the electrospray source have
been implemented. MS-MS (parent - daughter relationship) experiments
are routine. Equipment located in the facility includes a Finnigan
TSQ-700 GC-LC-MS, a Kratos MS-50 MS, a Finnigan Magnum ITD GC-MS,
and a Bruker Proflex DE MALDI-TOF.
X-Ray Diffraction
A completely equipped X-ray diffraction laboratory provides instrumentation
for the study of the molecular structures of small molecules.
The equipment includes a Bruker SMART-1000 CCD single crystal
diffractometer equipped with a low-temperature device, and a Scintag
SDS-2000 powder diffractometer available for general use. Complete
structure solution services are offered by our x-ray crystallographer,
or properly trained students may acquire data and use facility
computers and software to solve their own structures.
Spectrophotometry
A variety of spectrophotometers is available for routine use.
These instruments provide "fingerprint" spectra for
characterizing and identifying compounds. These instruments currently
include a Bruker IFS-66V FT-IR, a Digilab FTS-7 FT-IR, a Bomem
MB-100 FT-IR and an Hewlett Packard HP-8452 Diode Array UV-Vis.
Elemental Analysis
A Perkin-Elmer Model 2400 Series II CHN/S elemental analyzer is
available for sample submission. Normally the instrument is configured
for carbon, hydrogen, and nitrogen, but sulfer can also be analyzed
upon special request.
Computation
In addition to computer systems associated with the instrumentation
there are numerous Unix worksatations and PC's available for network-based
data processing, modelling, e-mail, WWW, et cetera.
