The Chemistry Department at UAF has a wide range of modern instruments available to undergraduate and graduate students. The instruments are used at all levels of instruction.
Professors in the department have been active in writing grant proposals to the National Science Foundation for purchase of new instrumentation.
1998: The department's Varian Mercury 300-MHz multinuclear NMR was obtained in 1998 by professors Clausen, Stolzberg, and Kennish (UAA) as part of an NSF Instrumentation and Laboratory Improvement Program. It is used in approximately five courses and in organic and inorganic chemistry research.
2000: Professor Keller, along with co-PIs John Kennish, Michael Stekoll (UAS), and Rudy Candler (UAA-Matsu) obtained NSF funding to set up computer labs in the chemistry departments all four UA campuses and install HyperChem molecular modeling software.
2004: Richard Stolzberg, Tom Green, and John Keller gained NSF funding from the Course, Curriculum, and Laboratory Improvement (CCLI) program for purchase of the HPLC and CE instruments shown below.
2007: John Keller and Todd Gouin were funded by NSF-CCLI for purchase of the Agilent GC-MS pictured below.
Varian Mercury 300 NMR Running VNMRJ
The 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 Running Topspin 3.0
The 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-MAS 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
The department currently (2007) has a Hewlett Packard 5890GC interfaced to a HP5972 mass selective detector. It is used for separating and identifying the components of volatile complex mixtures. The capillary column allow for separation of complex mixtures into individual components and database search software allows for identification of these components. It is has been used extensively for natural products chemistry and environmental chemistry research projects. Students in organic lab (Chem 324) and instrumental analytical chemistry lab (Chem 413) use the instrument as part of their regularly scheduled work.
Pictured at the right is a new GC-MS instrument slated for installation in early 2008. This machine is an Agilent 5975C GC-MS equipped with CTC CombiPal sample processing robot. The robot can inject various kinds of samples, 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 6890GC, with flame ionization detector and autosampler, which is used extensively for natural products chemistry research projects and organic chemistry lab (Chem 324) and instrumental analytical chemistry lab (Chem 413).
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.
This instrument was also obtained with NSF funding as part of a Separation Science package including new experiments for undergraduate laboratory classes. The CE separates liquid-phase molecules with an electric charge that migrate down a narrow capillary under the influence of a 10,000-volt electric field. Charged molecules such as amino acids, proteins, and nucleic acids are often separated by CE.
UV-Visible Diode Array Spectrometers
We have three Hewlett Packard 8452A and one Hewlett Packard 8453A diode array UV/VIS spectrophotometers for quantitative analysis of UV absorbing and visibly colored solutes. They all operate under the Windows ChemStation software.
We also have fixed wavelength spectrometers (Spectronic 21) for routine absorbance measurements.
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.
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.
Affiliated Instrumentation Centers
The Advanced Instrumentation Laboratory (AIL), has many additional analytical tools, which include:
Inductively Coupled Plasma Mass Spectrometer (ICP-MS)
X-ray diffraction (XRD)
X-ray fluorescence (XRF)
Fourier Transform InfraRed Microscope (FTIR-microscope)
Atomic Force Microscope (AFM)
Transmission Electron Microscope (TEM)
Scanning Electron Microscope (SEM)
microwave digestion apparatus
Computational Chemistry Servers - Gaussian 09, NWChem 6.1, and MOPAC 2012
The Department runs servers with Gaussian 09, NWChem 6.1, and MOPAC2012 software installed, with WebMO as the graphical user interface. Visit the server website for more information and FREE computational time as a guest!
Arctic Region Supercomputing Center
UAF's Arctic Region Supercomputing Center (ARSC) is also a regional center of the Department of Defense High Performance Computing Modernization Program. UAF academic research and teaching is carried out on two cluster computers, Midnight and Pacman. Gaussian 09 ab initio computational chemistry package is installed. GaussView software is used on chemistry department workstations to prepare input and examine output.
