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 />
