Analytical and Fabrication Services
A number of research laboratories at the Graduate School of Oceanography
(GSO) can provide analytical services on a per sample basis or by arrangement.
In addition, GSO has a machining and fabrication facility, seawater facilities,
and a pressure test facility that can be used, by arrangement, by persons
outside of the University of Rhode Island. In addition to facilities and
specific analytical services, arrangements may be made with individual
or teams of researchers to test materials, equipment, etc. For general
information or for inqueries concerning services that are not covered
in the list of analytical and fabrication services at right or below,

Equipment Development Laboratory & Pressure Test Facility
EDL has extensive high tolerance machining capabilities as well as welding, CAD design and assembly capabilities. EDL may be contracted for design and fabrication services. EDL also operates a pressure test faciltiy which may be contracted.
Trace element/isotope analysis of solids or solutions by ICP-MS.
The Inductively Coupled Plasma Mass Spectrometer (ICP-MS) provides rapid, high precision, simultaneous, multi-element analyses of solids, solutions, and slurries to part per trillion (ppt) levels in a variety of matrices including sea water, geological, metallurgical, aerosol, and biological samples. It can also identify, in a matter of minutes, most of the elements of the periodic table in a qualitative or semi-quantitative way.
GSO Paleomagnetics Laboratory
The Paleomagnetics Laboratory specializes in paleoenvironmental and paleoclimatic studies of sediments, as well as trace metal geochemistry of lacustrine, estuarine and marine environments. Analyses performed by the laboratory include: Magnetic properties of sediments; Trace metals; Grain size; Acid Volitile Sulfide;
CHN (carbon, hydrogen, nitrogen) analyses of particles, sediments, and tissues.
Analyses are done with a Carlo Erba EA1108 CHN analyzer. Sample preparation may be arranged. The cost is typically $3-5 per sample. For further information contact:
