Analytical Services

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


CHN Analyses analyses of particles, sediments, and tissues are done with a Carlo Erba EA1108 CHN analyzer. Sample preparation may be arranged. The cost is typically $9 per sample. For further information contact:
Dr. Bradley Moran
Telephone: 401-874-6530

The GSO ICPMS Laboratory is available for geochemical and environmental trace element analyses. The laboratory includes clean rooms for preparation of solution-based samples. The mass-spectrometers are a Finnigan Element High-Resolution ICPMS, 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:
