This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The multi-collector inductively coupled plasma mass spectrometer (MC-ICPMS) will be used to address cutting-edge questions related to solid earth, ocean, planetary, environmental, biological, medical and archeological sciences. The instrument is capable of analyzing precise isotope ratios not only on dissolved sample solutions, but also (when attached to a laser ablation system) allows in-situ analyses of almost any solid material with a spatial resolution of 10 microns (X-Y direction) and submicron depth-profiling resolution (using new excimer lasers). Such advanced capabilities in mass spectrometry are producing profound insights into a wide range of natural processes and the time scales over which they occur. The Brown MC-ICPMS will be the first instrument of its kind in the state of Rhode Island. The MC-ICPMS will serve a large science community and will function as a catalyst to foster inter-departmental and inter-institutional collaborations (Marine Biological Laboratories, University of Rhode Island, Roger Williams University and Bryant University) in research, education, and public outreach. The interdisciplinary environment at Brown University ensures that this new instrument will be applied to a broad array of scientific problems. Research efforts in isotope geochemistry are intimately linked with the education and training of the next generation of scientists. The MC-ICPMS instrument will provide our graduate and undergraduate students and those from other institutions access to state-of-the-art facilities and at the same time foster diversity among the ranks of future scientists. The Department of Geological Sciences and Brown University through the NSF GK-12, EPSCOR and Leadership Alliance Summer Research Early Identification Programs, are involved in a number of science education outreach programs that target under-served and under-represented groups in the community.

该奖项是根据2009年《美国复苏与再投资法》（公法111-5）资助的。多策略耦合等离子体质谱仪（MC-ICPM）将用于解决与固体，海洋，行星，环境，生物学，医学和考古科学有关的尖端问题。该仪器能够分析精确的同位素比，不仅在溶解的样品溶液上，而且（当附着在激光消融系统上时）允许对几乎所有具有10微米（X-y方向）的空间分辨率（X-y方向）和亚微米型脱位分辨率的固体材料的原位分析（使用新的移位激光液）。质谱的这种先进能力正在对广泛的自然过程和发生的时间尺度产生深刻的见解。 Brown MC-ICPMS将是罗德岛州同类工具的第一个工具。 MC-ICPM将为一个大型的科学界服务，并将充当催化剂，以促进部门间和机构间合作（海洋生物实验室，罗德岛大学，罗杰·威廉姆斯大学和布莱恩大学）在研究，教育和公共外展方面。布朗大学的跨学科环境可确保将该新工具应用于一系列科学问题。同位素地球化学的研究工作与下一代科学家的教育和培训密切相关。 MC-ICPMS仪器将为我们的毕业生和本科生以及其他机构的访问权限提供最先进的设施，同时促进了未来科学家队伍之间的多样性。地质科学系和布朗大学通过NSF GK-12，EPSCOR和领导力联盟夏季研究早期认同计划，参与了许多科学教育外展计划，这些计划针对社区中服务不足和代表性不足的群体。
