Instrumentation

The Chemistry Department at UAF has a wide range of modern instruments available for research, and  undergraduate and graduate instruction.

 Molecular Imaging Facility

The Molecular Imaging Facility provides access to state-of-the-art Magnetic Resonance techniques for the UA system. The facility has two NMR spectrometers: 300 MHz for solution studies, and 600 MHz for solutions or solids. The facility also has a 1.5 Telsa Magnetic Resonance Imaging (MRI) scanner that can be used for both imaging and spectroscopy, and a dual-energy X-Ray absorptiometry instrument for tissue studies.

Varian Mercury 300-MHz NMR Spectrometer

Varian Mercury 300The department has a 300 MHz Varian NMR for use in undergraduate labs (mainly organic chemistry) and research. It has a broadband probe tunable to most nuclei including hydrogen, carbon, fluorine, phosphorus, nitrogen, and vanadium. It is capable of one and two dimensional NMR experiments. It was obtained through a grant from the National Science Foundation Instrumentation and Lab Improvement (NSF-ILI) program.

 
 
Bruker AV-600 NMR Spectrometer 

Bruker AV-600 NMR Running Topspin 3.0The Department has a 600MHz Bruker NMR for use in research including undergraduate research. This system includes both a broadband liquids probe that can tune to most nuclei and an HR-Magic Angle Spinning probe designed for proton and carbon NMR on tissues and other semi-solids. It has a 60 position sample changer that allows for complete automation of experiments.

 
 
Gas Chromatograph with Mass Selective Detector

Gas Chromatograph with Mass Selective DetectorThe department has an Agilent 5975C GC-MS , which is used for separating and identifying the components of volatile complex mixtures. The capillary column allows for separation of complex mixtures into individual components that are analzyed by mass spectometry as they exit the column. Database searching software is used to identify the components. It is used mainly for environmental chemistry research projects, however  students in instrumental analytical chemistry lab (Chem 413) also use the instrument as part of their regularly scheduled lab.

The 5975C is equipped with a CTC CombiPal sample processing robot. The robot can inject various kinds of samples under computer control, including microliter volumes of liquids, vapor from the headspace of a closed sample bottle, or chemicals adsorbed on a solid phase microextraction (SPME) fiber.

We also have a Hewlett Packard 6890 gas chromatograph with flame ionization and electron capture detectors, and an autosampler. This is used for organic chemistry lab (Chem 324) and instrumental analytical chemistry lab (Chem 413).

High Performance Liquid Chromatograph (HPLC)

High Performance Liquid Chromatograph (HPLC)The Agilent gradient HPLC with UV/VIS diode array and mass-sensitive detectors is used for separating and identifying the components of nonvolatile complex mixtures. It complements the GC-MS, and is particularly useful in separating compounds of biological interest.

 
 
Capillary Electrophoresis

Capillary ElectrophoresisThis instrument was also obtained with NSF funding as part of a Separation Science package including new experiments for undergraduate laboratory classes. The CE  separates charged molecules that migrate down a narrow liquid-filled capillary under the influence of a 10,000-volt electric field. Molecules with a non-zero charge, such as amino acids, proteins, and nucleic acids, are often separated by CE.

 
 
UV-Visible Diode Array Spectrometers

UV-Visible Diode Array SpectrometersWe have three Hewlett Packard 8452A and one Hewlett Packard 8453A diode array UV/VIS spectrophotometers for quantitative analysis of UV-absorbing and colored solutes.

 

 

 

 

 

Fourier Transform Infrared (FT-IR) Spectrometer

A research-quality Thermo Scientific Nicolet iS50 FT-IR spectrometer is used for structural characterization of organic compounds and for quantitative analysis of certain gaseous and liquid phase solutes in organic, analytical, and physical chemistry labs. We have a 10-m gas sampling cell and sampling hardware for diffuse reflectance, attenuated total reflectance, and external reflectance geometries.

Computational Chemistry

The department has several servers running Gaussian, NWChem, and MOPAC computational packages. Web access is provided by the WebMO program.  This system is used by students in undergraduate labs and in undergraduate,  graduate, and faculty research projects. Visit the  UAF Chemistry Computational  information page

Research Computing Systems (RCS) at the Geophysical Institute provides advanced computing, storage, data sharing solutions and research IT support to University of Alaska research communities, collaborators and supporters. RCS has installed the Gaussian computational package on their Chinook HPC cluster. Gaussian can be accessed via their WebMO portal

Other Instrumentation

The Department has Sorvall RC5B centrifuges and a Beckman Optima LE-80K ultracentrifuge. A variety of balances, ultra-low freezers, about 40 large fume hood-protected benches, and a large chemical storage facility are also available. Biochemistry research labs contain cell culture facilities, sterilizers, a confocal fluorescence microscope, and other specialized equipment.
