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.

该奖项根据 2009 年美国复苏和再投资法案（公法 111-5）提供资金。多接收器电感耦合等离子体质谱仪（MC-ICPMS）将用于解决与固体地球、海洋、行星、环境、生物、医学和考古科学相关的前沿问题。该仪器不仅能够分析溶解样品溶液的精确同位素比率，而且（当连接到激光烧蚀系统时）还可以对几乎任何固体材料进行原位分析，空间分辨率为 10 微米（X-Y 方向）和亚微米深度剖面分辨率（使用新型准分子激光器）。质谱分析中的这种先进功能正在对各种自然过程及其发生的时间尺度产生深刻的见解。 Brown MC-ICPMS 将成为罗德岛州首个此类仪器。 MC-ICPMS 将服务于大型科学界，并将作为促进研究、教育和公共宣传方面的跨部门和机构间合作（海洋生物实验室、罗德岛大学、罗杰威廉姆斯大学和布莱恩特大学）的催化剂。布朗大学的跨学科环境确保了这种新仪器将应用于广泛的科学问题。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 仪器将为我们的研究生和本科生以及其他机构的学生提供最先进的设施，同时促进未来科学家队伍的多样性。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识别计划参与了许多针对社区中服务不足和代表性不足的群体的科学教育推广计划。
