Instrumentation

 The following list describes the use of major instrumentation in the Department of Chemistry. Research faculty also have additional instruments related to their research areas.

1.      Microwave systems. The Chemistry department has six state-of-the-art commercial microwave systems.: a CEM MDS 2000, two CEM MDS 2100, a Biotage Initiator microwave system, a CEM Explorer Microwave System and a CEM discover microwave systems.

2.      Bruker 400 MHz NMR spectrometer is used in physical, chemical, electronic and structural characterization of molecular systems. The NMR spectrometer was acquired through the previous NSF-RISE funding in 2002 and since has been the one of the most important instrumentation for the successful completion of the research projects in the NSF-RISE programs.

3.      UV-Vis spectrometer is used in the determination of conjugated dye systems, compound analysis of and optical studies, surface plasmon resonance peaks of metal, metal oxide and hybrid nanostructures, etc. The Chemistry department has several UV-Vis spectrometers: a Perkin Elmer UV/VIS lambda 10, a Varian Cary UV/VIS Bio100, a Varian Cary Eclipse Fluorometer with HTS and polarizer accessories and an Ocean Optics Jaz Spectrometer.

4.      Fourier transform infrared spectroscopy (FT-IR) is used in the determination of functional groups of molecular systems. The Chemistry department has three FT-IR's and they are in excellent working order: a Nexus 670 FT-IR Near-Infrared Spectrometer, a Nexus 870 n FTIR capable of 2-D near-IR spectral analysis, a Digilab FTS 8000 FTIR with step-scan capabilities and the ability to be adapted for FTIR microscopy imaging analysis.

5.      Spectrofluorometers are used for the characterization of spectral and lifetime properties of the molecular systems. Spectral properties such as absorbance and emission maximum wavelengths of detection, Stokes shifts, and luminescence lifetimes are used to address the various requirements associated with different analytical techniques (i.e. instrument compatibility, ratiometric and multicolor labeling, multi-lifetime labeling).  The Chemistry department has two , an Ocean Optics USB 4000 and an Ocean Optics Jaz High-Resolution Fluorescence Spectrophotometer and a Applied Spectroscopy Lab PTI Easylife FluorescenceTime-Resolved Lifetime instrument. In addition several light sources are available to be used with these spectrofluorometers.

  6.      The Chemistry department has a TA Instrument's 2990 Micro Thermal Analyzer with SFM and AFM capability and a Gel Permeation Chromatography (GPC) System, which are used in studying surface properties and surface thermal profiles of nanostructures, composite and polymeric materials.

7.      High Pressure Liquid Chromatography (HPLC) and Gas chromatography-mass spectrometry (GC-MS) are used in the purification and product selectivity of molecular systems. The Chemistry department has five HPLC's and they are in excellent working order.

8.     Laser systems:  Coherent Mira 900-F Ti:Sapphire laser, pumped by a 5 Watt Verdi solid-state laser, is available for multiphoton excitation. The Ti:Sapphire laser is close to the Fluorolog 3 spectrofluorometer, which can be used to excite samples.

 9.      Scanning Electron Microscopy and Atomic Force Microscopy are used to characterize nanostructured and macroscale materials . The Chemistry department has access to these instruments through The School of Computer Mathematics and Natural Sciences (SCMNS).
