NMR Spectrometer

A picture of the NMR

The Department's Dual Probe 300MHz JEOL Eclipse Nuclear Magnetic Resonance (NMR) spectrometer is an integral part of the group's research activities. The instrument is equipped with an 8-slot sample changer, a Silicon Graphics workstation, variable temperature, and 2D capacity.The instrument was purchased through a grant from LEQSF and matching funds from the University and TASC.

FTIR Spectrometer

A picture of the FTIR

A MIDAC M1200 Fourier Transform Infrared Spectrometer is capable of providing infrared spectra to a resolution of one reciprocal centimeter. FTIR is useful in identifying functional groups in compounds and for routine analysis since each compound has its own characteristic "finterprint". A second MIDAC M1200 is also housed in the Chemistry Department. These instruments are used for both lab classes and research.

The 166 MHz Gateway 2000 computer shown contains interface cards for both the MIDAC 1200 and the Hewlett Packard 6890 Gas Chromatograph shown on the next page. Both the FTIR and the GC are controlled by this computer.

Gas Chromatograph

A picture of the GC

This Hewlet Packard 6890 Gas Chromatograph system uses capillary columns and has both temperature programming and pressure programming capabilities. The instrument utilizes a flame ionization detector. GC is useful in separations of mixtures for analytical purposes. The instrument is used both for undergraduate teaching and for research.


A picture of the GC/MS

This Hewlett Packard Gas Chromatography-Mass Spectrometry System consists of a Hewlett Packard 6890 Gas Chromatograph coupled to a Hewlett Packard 5973 Mass Selective Detector (quadrapole type). The system is controlled by a 150 MHz Hewlett Packard computer with the capability of archiving GC-MS data to writable CDS. GC-MS is useful in separations of mixtures for analytical purposes and identifying unknown compounds. The system is used for both research and for undergraduate teaching.


A picture of the HPLC

The Varian Dynamax SD-200/SD-300 High Performance Liquid Chromatographic System can perform analytical and semi-preparative separations of organic and biological samples. It can run programmable gradient and isocratic elutions and possesses variable temperature capacity. The system is equipped with UV-Visible and refractive index detectors and is fully computer-interfaced. In tandem with the GC, the HPLC gives students first-hand experience with the two most powerful and most commonly used chromatographic techniques in industry and research. It also allows students to view how chromatography can be used in an analytical sense to aid in the identification of compounds, and in a preparative sense for purifications of mixtures of compounds.


This is a double-beam, semi-automatic, computer-controlled atomic absorption spectrometer. Over 70 elements can be analyzed at ppm to ppb levels by flame atomic absorption.

Perkin Elmer 3100 AA

The Perkin Elmer 3100 atomic absorption spectrometer is a double-beam, semi-automatic, computer-controlled atomic absorption spectrometer. It can anayze over seventy elements at ppm to ppb levels.

Perkin Elmer 5100 AA

The Perkin Elmer 5100 atomic absorption spectrometer is equipped with two atomizer modules for different types of non-flame analysis in addition to standard flame atomization. One is a 5100ZL zeeman furnace module with HGA 600 zeeman graphite furnace atomizer and AS70 autosampler for trace metal analysis; the other is a FIAS 200 hydride analyzer mercury and hydride-forming elements with a AS90 autosampler. Each module is computer selected and controlled. Atomic absorption spectrometry is capable of analyzing for over over seventy elements at the sub-ppm and ppb level.

Thermo Jarell Ash Smith-Heifte 8000 AA

This AA is equipped to do multi-element analysis of eight elements simultaneously. It can operate in either the flame or flameless graphite furnace mode. It is equipped with a graphite furnace analyzer employing Smith-Hiefte background correction.

Computer Assisted Labs

Students in the freshman lab program use this computer-interfaced experiment to simultaneously see an acid-base reaction as it occurs and the graph of its titration curve generated on the computer screen. During the post-lab analysis they examine print-outs of the titration curves for strong and weak acids.
