Facility and Equipment in the Lab
|
Fourier Transform InfraRed MicroscopeThe Planetary Exploration Group Lab has a Thermo Scientific iN10 FTIR microscope in the mid-infrared range for spectral analyses in transmission, reflectance, and absorbance. The spectral range is from 7,800 to 450 cm-1 at a scale between 10 and 400 µm.
Room temperature DLaTGS detector: analyses down to 50 µm Cooled MCT-A detector: higher sensitivity and analyses down to 10 µm |
Fourier Transform Visible-Near InfraRed/ Mid-InfraRed MicroscopeThe lab houses a Nicolet 6700 FTIR upgraded from a Nexus 670 for spectral analyses in transmission, reflectance, and absorbance from 12,000 to 450 cm-1 at a scale between 16 µm and 2 mm.
DTGS Mid-Infrared detector: 7,000 to 450 cm-1 InGaAs Visible/Near Infrared detector: 12,000 to 6,000 cm-1 Czitek Survey IR microscope accessory |

Gas-Mixing Furnace and Sample Preparation
The lab also houses a Deltech 1-atm gas mixing vertical tube furnace for crystallization experiments. Samples can be exposed to air, inert gas or a CO/CO2 mixture and heated up to 1700 °C.
All the necessary preparation equipment is available in the lab and the Department's Petrographic Facilities. Facilities includes petrographic microscopes, high-precision balances, diamond saws, specialized grinding equipment, and polishing wheels.

Workstations
The computer lab includes 2 Windows workstations, 1 Mac desktop, and 1 Fedora Linux workstation. The workstations all have image manipulation software including Adobe Suite and word processing capabilities in MS Office, and spectral processing software including davinci (http://davinci.asu.edu), QGIS and ArcGIS Pro, and ENVI/IDL.
Analytical Instrumentation at the University of Iowa
|
The MatFab facility at the University of Iowa hosts several instruments for chemical and mineralogical analyses. Instrumentation includes an electron probe microanalyzer JEOL JXA-8230 Superprobe, a Rigaku X-ray Fluorescence (XRF) spectrometer, and two ICP-MS for chemical analyses, two X-ray diffractometers and a Raman microscope InVia Renishaw for mineralogical analyses, and a Hitachi Scanning Electron Microscope (SEM) for imaging.
