The Plasma Facility specializes in high precision isotopic and elemental analyses of small or dilute samples. Our capabilities include high precision measurement of radiogenic isotopes (e.g. Sr, U, Th, Pb, etc.) and non-traditional stable isotopes (e.g. Ca, Fe, Si, Cr, Mg, etc) using the Nu Plasma HR multi-collector ICP-MS or the Finnigan MAT 262 TIMS. We also have the capability to measure the elemental composition of a wide variety of dissolved materials using the Nu Attom high-resolution ICP-MS. As these capabilities come on-line, we will provide more specific information.
