College/Unit: COLLEGE OF LIBERAL ARTS AND SCIENCES

Description:

This facility provides analytical capabilities to measure light stable isotope ratios (H, C, N, O, and eventually S) by IRMS, radiogenic (Hf, Sr, Nd, Pb) and mass-dependent isotopes (Ca, Cr, Fe, Ni, Cu, Zn, Rb, Sr, Zr, Mo, Cd, Hg, Pb, U) by MC-ICP-MS and elemental concentrations (row 3 and above) by Q-ICP-MS. Mass spectrometers include a Thermo Electron DeltaPlus Advantage (IRMS), a MAT 253 (IRMS), a Thermo Electron X-Series with CCT (Q-ICP-MS) and a Thermo Electron Neptune (MC-ICP-MS), . Users are trained to run their own samples and process the results with lab supervision. Some of the peripheral devices available include an Elemental Analyzer, TC/EA, Gasbench, Dual Inlet, TIC/TOC analyzer, and some accessories. There is also a trace-metal clean lab which may be available for sample preparation. Users are encouraged to get involved with method development to expand the analytical applications available here.
