Trace-Element Geochemistry Laboratory

Its center is a Perkin Elmer Elan 6100 Inductively Coupled Plasma Mass Spectrometer (ICP-MS).  Only a few mL of liquid sample are needed for quickly measuring most elements with sub parts-per-billion detection levels.  A Cetac LSX-200 plus laser ablation sampler allows direct ICP-MS analysis of solids such as minerals and rocks.  We also have an Parr Microwave Digester for dissolution of rocks, sediments, and minerals for ICP-MS analysis.  Other instruments include a Dionex Ion Chromatograph.  Funding for this lab was through a grant from the Department of Defense.



Scanning Electron Microscopy Laboratory

Established in 2007, the lab houses a Hitachi S-3400 variable pressure scanning electron microscope (SEM) equipped with an Oxford Inca energy dispersive x-ray spectrometer (EDS) and Gitan ChromaCL live color catholuminescence (CL) imaging system.  The EDS detector measures the elemental composition of samples and the CL detector shows subtle, otherwise invisible textures such as zonation in crystals.  Funding for this lab was through a grant from the Department of Defense.



X-Ray Diffractometer

The  PANalytical Empyrean  X-Ray Diffractometer isused for the identification of minerals in soils and sediments by powder X-Ray diffraction.  Funding for this instrument was through a 2015 grant from the National Science Foundationís Major Research Instrumentation program.



Field Equipment

We have a full range of field equipment and instruments for the collection of water, soil, and sediment samples, and field measurements.  This includes a Gidding coring rig for the collection of sediment cores and the installation of shallow monitoring wells.  Funding for the coring rig was through a grant from the National Science Foundation.
