Instrumentation<br />
The department has significantly upgraded its mass spectrometric<br />
<strong>in</strong>strumentation with the acquisition of the follow<strong>in</strong>g<br />
systems: (1) A Kratos laser desorption time-of-flight (MALDI-TOF) mass<br />
spectrometer with l<strong>in</strong>ear and reflectron modes, (2) A Shimadzu gas<br />
chromatograph mass spectrometer with both electron-impact and electron<br />
ionization, and (3) A Thermoquest/F<strong>in</strong>negan electrospray ionization mass<br />
spectrometer (ESI-MS), fitted with a liquid chromatograph and with the<br />
capability for multiple mass spectral analyses. These <strong>in</strong>struments<br />
compliment our VG 70S high-resolution GC-mass spectrometer, which is<br />
capable of FAB, DCI, EI, and CI spectrometry. The department also<br />
ma<strong>in</strong>ta<strong>in</strong>s a Bruker EMX 10 /2.7 EPR spectrometer (X band and low<br />
temperature)<br />
In addition to computers and workstations dispersed throughout<br />
all the <strong>in</strong>dividual research groups, a dedicated computer lab is housed <strong>in</strong><br />
Remsen Hall, with access available to all students, staff, and faculty.<br />
Many of the faculty research laboratories have purchased or<br />
constructed highly specialized <strong>in</strong>strumentation tailored to their specific<br />
research objectives. These <strong>in</strong>clude the follow<strong>in</strong>g: several molecular beam<br />
apparatus, negative ion photoelectron spectrometers, ultra-high vacuum<br />
surface analysis chambers with Auger electron and X-ray photoelectron<br />
spectrometers, an atomic-force microscope, a time-resolved <strong>in</strong>frared<br />
spectrometer, numerous laser systems (Nd:YAG, excimer, dye, optical<br />
parametric oscillator, argon ion), a phase fluorimeter, a fluorescence<br />
microscope, and nanophase material generators.<br />
