The College of Geosciences Radiogenic Isotope Geochemistry Laboratory is currently under construction with an expected completion date of April 2008. The facility will contain Class 100 and 1000 ultra-clean chemistry laboratories, a mass spectrometry lab, and a sample preparation lab (2600 square feet). The clean laboratories are designed for low-blank (contamination free) chemical preparation of samples for U, Th, Pb, Sm-Nd, Re-Os, and Sr isotopic analyses. The mass spectrometry lab will house a new Thermo Scientific Triton thermal ionization mass spectrometer (TIMS) with space to accommodate two additional instruments: a high-resolution, inductively-coupled plasma mass spectrometer (HR-ICP-MS) with a laser ablation system (Major Research Instrumentation proposal to NSF pending), and a multi-collector inductively-coupled plasma mass spectrometer (MC-ICP-MS). The lab instrumentation will serve the research needs of a broad range of disciplines, including tectonics, geochronology, paleoceanography, climate change and environmental geochemistry. Drs.
