Desktop-size low-voltage electron microscope with SEM, TEM, STEM, and ED modes.
This Nuclear Magnetic Resonance Spectrometer was purchased in 2001 with a grant from the University of Nebraska Foundation. It includes a broadband probe, variable temperature controller, Z-gradient 2-D acquisition, and network capabilities.
TA instrument NANO ITC
Agilent 7820 A GC-MS with autosampler. This instrument includes an autosampler and enhances molecular structure characterization capabilities in our organic and analytical chemistry areas.
This Spectrum One liquid-nitrogen cooled CCD array spectrograph is outfitted with both 600 groove/mm and 2400 groove/mm gratings. In normal resolution mode (for fluorescence measurements) the instrument has a resolution of 0.15 nm throughout the ultraviolet-visible spectrum. It is capable of achieving signal to noise ratios in excess of 10,000 in a fraction of a second while simultaneously measuring all wavelengths in a 150-nm window. In high resolution mode (for Raman spectroscopy), the instrument has a resolution of 0.035 nm (about 1.5 cm-1 near 488 nm). Excellent quality spectra can be taken in about one minute for pure samples or a few minutes for proteins in solution.
Jasco J-810 circular dichroism spectropolarimeter
Custom-built vapor deposition apparatus. This custom-built apparatus is used to selenize and anneal (heat) solid-state materials samples. The 8000W Quad Ellipse Chamber Heater shown has manual and computer temperature control options with a maximum heating temperature of approx. 1000 oC. The tubular quartz sample chamber may be evacuated or flushed with a gas of choice.
The differential scanning calorimeter measures heat transfer during material phase changes.
Horiba Jobin Yvon FluoroMax-4 steady-state fluorescence spectrometer
FT-IR spectrometer. This instrument scans in the near-, mid-, and far-infrared regions with resolution down to 0.09 cm -1 and scanning speeds up to 65 scans per second. Detectors employed are a liquid nitrogen-cooled MCT (mercury-cadmium-telluride) detector for the near- and mid-IR regions and a polyethylene film detector for the far-IR region. Included are three beamsplitters: quartz (near), KBr (mid), and solid substrate (far). The department also has the following sampling accessories: traditional disk and solution cell holders, diffuse reflectance, specular reflectance (fixed 30 deg and a VeeMax II accessory for variable 30-80 degree incidence), and horizontal attenuated total reflectance (HATR). Classes and research groups utilize this instrument for characterization of organic and inorganic chemical reaction products as well as thin solar cell material films. Instrument features include spectral substraction, mathematical correction, baseline correction, and a library of thousands of reference IR spectra.
