Instrumentation

Maldi In ClassChemistry students routinely use sophisticated instrumentation, including a Bruker multinuclear 400 MHz nuclear magnetic resonance spectrometer, a Varian Vista MPX inductively coupled plasma (ICP) spectrometer, and an IonSpec HiRes Matrix Assisted Laser Desorption/Ionization (MALDI)-Fourier Mass Spectrometer (FTMS). The MALDI- FTMS is the only instrument of its kind at an undergraduate institution.

The department maintains a broad spectrum of state-of-the-art instrumentation that are kept up-to-date and are maintained by our instrument support technician, who also provides training on all instruments.

Other departmental resources include a microwave digestion system (CEM Mars5), freeze dryer (Labconco), surface area analyzer (Gemini), an Agilent Flash Purification System (971FP), a capillary electrophoresis (Agilent CE G1600A), facilities for time- resolved luminescence and low temperature (4.2 K-room temperature) optical spectroscopy and a Vacuum Atmospheres inert-atmosphere workstation with an integrated gas purification system. The department has its own laboratory computers which are available to students for advanced molecular modeling and computational chemistry using the programs Spartan, Gaussian, and Amsterdam Density Functional. These computers form an integral part of advanced coursework and are used extensively in student research projects.

Computer Resources

The department has a large number of laboratory computers (both PC's, and Mac's) that are used for data manipulation and acquisition. There is also a cluster of dual boot PCs that are available to Chemistry, Biochemistry and Biology majors for advanced molecular modeling and computational chemistry. Students have access to molecular computation programs (Spartan, Gaussian, Macromodel, ADF) running on eight- or four-processor clusters tied to a disk array, as well as programs for advanced data analysis (Mathematica, SigmaPlot, SpectraCalc). These computers and software packages are important elements of course work and are used extensively in student research projects.
