Dionex DX-500 Ion Chromatograph:  Operated and maintained by the Diagenesis Research Group; located within the departmental (EPS) chemistry lab. The IC is used to measure anion concentrations (e.g., chloride, bromide, nitrate, sulfate...) from ground waters.

Atomic Absorption Spectrophotometer:  Part of the analytical facilities available within the Department of Earth and Planetary Sciences chemistry lab, which is run by John Husler. The AA is used to measure cation concentrations (sodium, magnesium, potassium, iron...) in solutions.

Spectrophotometer:  For colorimetric methods. We use a portable Hach DR-2000 spectrophotometer to analyze unstable redox-sensitive solutes in the field.

Field Equipment:  Various probes for measuring a number of groundwater parameters in the field (dissolved oxygen, conductivity, oxidation-reduction potential, pH, temperature...), multi-level samplers, pumps and filtering equipment, and a "beeper" for down-hole groundwater depth measurements.

Scanning Electron Microscope with Energy-Dispersive X-ray Spectroscopy, and Electron Microprobe:  The Department of Earth and Planetary Science and Institute of Meteoritics Electron Microscopy lab, run by Mike Spilde.

X-Ray Diffractometer:  A Department of Earth and Planetary Sciences facility, run by Jim Connolly. Used in clay mineralogy studies.

X-Ray Fluorescence: A departmental facility, overseen by John Husler. Used for determining major element oxides of rock/sediment samples.

Clay Preparation Facilities:  Located within the Diagenesis Research Group's laboratory. Facilities include centrifuges for sediment size separation, and a millipore filtration system for clay mounting for X-ray diffraction.

Petrographic Microscope:  Located within the Diagenesis Research Group's laboratory. Contains a Polaroid camera attachment for instantaneous photos, a 35 mm camera attachment, and a Swift automated point counter. Digital camera attachments are available elsewhere in the Department.

Cathodoluminescence (CL) Unit: A companion to the petrographic microscope, this Nuclide Luminoscope is useful for looking at CL properties of quartz, calcite, feldspar, and other minerals.

Diagenesis Research Group Facilities:  Several PC's are available for general work with spreadsheets, word processing, data processing, statistics, and graphic design. Additional available software includes: RockWorks 99 for geological data management, analysis and display; Adobe Photoshop for image analysis and paper/presentation preparation; Microsoft PowerPoint; Adobe Acrobat; Geochemist's Workbench; and PHREEQC. PHREEQC is used for geochemical modeling in aqueous systems.
