Acquisition of a Quadrupole Inductively Coupled Plasma Mass Spectrometer, Ultraviolet Laser Lab and Sample Imaging Unit

这笔拨款为购买磁性扇形电感耦合等离子体质谱计（HR-ICP-MS）和紫外线激光器提供了部分支持，这些设备将被安置在马里兰大学帕克分校的地质学系。激光辅助和基于溶液的ICP-MS分析将帮助PI和许多其他院系的研究人员研究地壳和地幔的地球化学演化、宇宙化学研究、附属相的U-Pb地质年代学、碳酸盐岩石学、实验岩石学以及地表水和地下水的生物地球化学。该仪器将补充该部门现有的地球化学仪器，包括稳定同位素比质谱仪、热电离质谱仪、多收集器ICP-MS和电子束仪器。大量接受过地球化学培训的教师（其中许多是新任命的）和最先进的地球化学仪器使马里兰大学-科罗拉多州立大学在未来的许多年里，在地质科学的研究和本科生和研究生的培训方面都处于领先地位

0004095McDonoughThis grant provides partial support for the acquisition of a magnetic sector-based inductively coupled plasma mass spectrometer (HR-ICP-MS) and an ultraviolet laser to be housed in the Geology Department at the University of Maryland, College Park. Laser-assisted and solution-based ICP-MS analysis will aid the research of the PI's and numerous other departmental faculty in studies of the geochemical evolution of the crust and mantle, cosmochemical research, U-Pb geochronology of accessory phases, carbonate petrology, experimental petrology and the biogeochemistry of surface and groundwaters. This instrument will complement existing geochemical instrumentation in the department including stable isotope ratio mass spectrometers, thermal ionization mass spectrometers, a multi-collector ICP-MS, and electron beam instrumentation. The critical mass of faculty trained in geochemistry (many newly appointed) and the arsenal of state-of-the-art geochemical instrumentation leave UMD-CP well poised to be leaders in both research and the training of undergraduate and graduate students in the geological sciences for many years to come.***
