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.
