Analytical Services

A number of research laboratories can provide analytical services on a per sample basis or by arrangement.


CHN Analyses analyses of filtered particles, sediments, and tissues are done with an Exeter Analytical CE-440 elemental analyzer. Sample preparation may be arranged. Please inquire regarding cost per sample. For further information contact:
Dr. Bradley Moran
Telephone: 401-874-6530
moran@gso.uri.edu

Organic Compounds and Black Carbon Analyses: Organic analysis of petroleum compounds, biomarkers, and environmental organic contaminants are done with an Agilent GC-MS or a Waters' GC-MS/MS for compound identification and quantification. Extensive QA/QC protocols are in place for a wide range of organic contaminants, including PAHs, alkanes, PCBs, OCPs, dioxins and furans, PBDEs, triclosan and other emerging contaminants. In addition, soils, sediment, and filter samples can be analyzed for black carbon using either CTO-375 or pyrene fluorescence loss method. The laboratory has complete extraction and preparation facilities for water, tissue or sediment/soil samples, including ASE extraction and several Turbovap units. For further information contact:
Dr. Rainer Lohmann
Telephone: 401-874-6612

Radionuclide Geochemistry Laboratory is capable of low-level detection of alpha, beta and gamma emitting radionuclides. Radionuclides typically analyzed include Th-234, Th-230, Th-228, Th-232, Pb-210, Cs-137, Be-7, Ra-224, Ra-223, Ra-228, Ra-226 and Rn-222. Sample preparation (water or sediment) may be arranged.

The GSO ICPMS Laboratory is available for geochemical and environmental trace element analyses. The laboratory includes clean rooms for preparation of solution-based samples and a Thermo X-Series II Quadrapole ICPMS. Sample introduction apparatus include: standard and low-flow nebulizer/spray chambers; Desovating Nebulizer; Hydride Generator; and a New Wave UP-213 Laser Ablation System. The laboratory is open to University and outside users. For further information contact:
