The Soil Chemistry Laboratory is currently
under construction and will contain a wide variety of equipment and
instrumentation. Anaerobic chambers (gloveboxes) are available for
research requiring anoxic , or low-carbon dioxide. A variety of
analytical tools are available, including X-ray diffraction, Raman spectromicroscopy and infrared spectroscopy for sample characterization, and
an inductively coupled plasma optical emission spectrometer (ICP-OES) for
routine measurement of solute concentrations.

Much of the research
conducted in the Soil Chemistry group involves the use X-ray spectroscopy.
This technique is an element-specific, in-situ probe of the structure
of materials. As such, it is useful to speciate both contaminants and
other elements in complex, geologic and soil matrices. This research
is conducted at synchrotron radiation sources at
Stanford University,
Argonne National
Laboratory, and
Brookhaven National Laboratory. |

In addition to these facilities, others in the Department of Earth
Sciences are available if needed. These other facilities are described
below:
|
Trace Element Geochemistry |
Provides inductively-coupled plasma-mass spectrometry (ICP-MS)
and other analyses of elemental composition |
|
Stable
Isotope Laboratory |
Provides a suite of mass spectrometers to determine the
isotopic composition of both solids and liquids |
| Rippel
Electron Microscopy Facility |
A facility providing both Scanning Electron Microscopes
(SEM) and Transmission Electron Micorscopy (TEM) analysis to the
Dartmouth Community |
