Equipment

Magnetic Resonance instruments include a Bruker EMX-200 EPR equipped with single and dual cavities, liquid helium dewar, and liquid nitrogen accessories, a Varian Mercury 300 for routine 1H, 13C, 19F, 31P, and Varian Inova 300, 400 and 500 instruments equipped with pulsed field gradients, VT, and a variety of probes for doing nearly any high resolution nmr method and micro-imaging (at 500 MHz). The undergraduate laboratories are equipped with a Varian Gemini2000 broadband 300 MHz NMR for instruction.

Mass spectrometry instruments include a 2001 Agilent 5973 Mass Selective Detector with 5890 GC, autosampler and PC based data-system, a 1992 Fisons VG Quattro-SQ single quad mass spectrometer equipped for Electron Impact, Chemical Ionization and Electrospray, a 1993 Fisons VG Quattro-TQ triple quad mass spectrometer equipped for Electron Impact, Chemical Ionization and Electrospray, a 1992 Fisons VG AutoSpec double focusing, high resolution instrument equipped for Electron Impact, Chemical Ionization, GC/MS, Liquid Secondary Ion Mass Spectrometry, and Field Desorption. and a 2000 Finnigan LCQ-Duo ion-trap mass spectrometer equipped with a Hewlett-Packard 1100 series HPLC.

Our materials and surface characterization lab has a 1999 Nicolet Magna-760 FT/IR with Raman module, an Auxillary Experiments Module (AEM) with Grazing Angle Reflectance and Attenuated Total Reflectance accessories, and a Continuum IR-Microscope. The lab has a 2000 Varian Cary-500 UV-VIS-NIR spectrophotometer equipped with both a Praying Mantis and Variable Angle Specular Reflectance accessory, and a 1999 Woollan HS-190 variable angle spectroscopic ellipsometer. The lab is equipped with three instruments from Thermal Analytics (1999) including 2950 thermogravimetric analyzer (TGA) with integrated Balzers mass spectrometer, a modulated DSC and DTA cells, and a 2970 dielectric analyzer (DEA). The laboratory also has a 1999 Scintag X2 powder X-ray diffractometer with Peltier detector, a 2000 Bruker D8-Discover surface X-ray diffractometer with seven axes of motion and Gšbel Mirror on the primary beam side, and recently acquired a 2000 Physical Electron 5800 ultra-high vacuum XPS-Auger spectrometer.

A 2004 SQUID AC/DC magnetic susceptibility instrument, MPMS-XL includes: a high homogeneity magnet configuration of ± 5.0 Tesla; a reciprocating sample measurement system for improved sensitivity and measurement speed, continuous low temperature control/temperature sweep with enhanced thermometry for continuous operation below 4.2 K, AC susceptibility measurements from 0.1 Hz to 1 KHz with a sensitivity of 2 x l0-8 emu at 0 T, a reciprocating sample option (RSO) - DC magnetization absolute sensitivity of 1 x 10-8 emu at 2,500 Oe. The system is capable of temperature sweep rates from 0.001 -  10 K/min, and is equipped with a magnet reset option and liquid nitrogen jacketed dewar.

A 2002 FESEM or field emission scanning electron microscope offering: JEOL JSM-6500F, high resolution (1.5 nm at 15 kV/5.0 nm at 1 kV), a multi-purpose sample chamber, a motorized, automated sample stage, one-action sample exchange, energy dispersive spectroscopy (EDS) from Thermo Electron and an NPGS electron lithography system which allows for writing patterns with line width less than 5 nm.

Laboratory Space

The Central Instrument Facility (CIF) occupies 3,400 square feet of contiguous space in the basement of the Chemistry Department. This area was remodeled and upgraded by the University in 1999 ($350,000). There are four distinct lab areas requiring key-access including the high-field nmr lab (400 sq. ft.), the XRD lab (250 sq.ft.), the UHV-XPS lab (500 sq. ft.), and main lab (2,250 sq. ft.). In addition, the CIF maintains a small lab on the 3rd floor of the Chemistry Department for the Varian Mercury-300 spectrometer (100 sq. ft.) and a lab in the Anatomy and Physiology Department for the SEM (200 sq. ft.). In addition to floor space, benches, and the like there is a sample preparation area with a chemical fume hood and sink. The laboratory is supplied with a 180 psi source of clean, dry N2 gas from liquid-N2 boil-off which is used exclusively for apparatus in the CIF.

Computers

The Central Instrument Facility (CIF-2001) has about 36 computers, most of which are involved directly in instrument control. Most of these are less than three years old. Each staff member has a personal computer on their desk, none more than three years old, equipped with the latest report writing and data processing software, according to staff needs. Sun Microsystems  computers  are available for general purpose NMR data processing. The CIF maintains  a "www" web and instrument reservations server. The entire CIF computer network is connected by two 3-COM¨ 3300 switches under CIF administration and control. The Department of Chemistry maintains a firewall appliance that provides  advanced security features aimed at reducing the threat of intrusion and "hacking". The Department also has a computer facility separate from the CIF which is professionally staffed and equipped with the latest hardware and chemistry modeling software available. This facility is available 24 hours per day year around. Other professional and customary computer services are available from the Academic and Computing Network Services (ACNS) on campus.
