The multi-collector inductively coupled plasma mass spectrometer (MC-ICP-MS) funded by this MRI award enables a team of scientists at Indiana University to investigate metal isotope fractionation effects and the chemical mechanisms governing metal isotope fractionation in a variety of environmental, biological, geological, and planetary contexts. Undergraduate, graduate, postdoctoral, and faculty researchers in Geological Sciences, Chemistry, and the School of Public and Environmental Affairs, as well as collaborators from two nearby primarily undergraduate institutions (Indiana State University and DePauw University), will use this cutting-edge instrumentation to advance understanding of how metal isotopes trace and record chemical, geological, and biological processes occurring in nature. This understanding will in turn enable application of metal isotope geochemistry to a wide range of important questions, including those related to contaminant metal fate and transport, availability of bioessential metals in natural waters and sediments, origin of ore deposits, and records of early life on Earth and other planets. The MC-ICP-MS will be located in the recently completed Multidisciplinary Science Building II, which also contains a newly constructed, dedicated clean room for experimentation and sample preparation. The instrument shares space with a well-established and internationally recognized gas-source mass spectrometry facility and thus extends the analytical capabilities of that laboratory across the entire periodic table. These facilities and hands-on training from a partially NSF-supported technician will aid in preparation of the current and next generation of young scientists.

由该MRI奖资助的多收集器电感耦合等离子体质谱仪（MC-ICP-MS）使印第安纳州大学的一组科学家能够研究金属同位素分馏效应以及在各种环境，生物，地质和行星背景下控制金属同位素分馏的化学机制。本科生，研究生，博士后和教师研究人员在地质科学，化学和公共和环境事务的学校，以及来自附近的两个主要本科院校（印第安纳州州立大学和DePauw大学）的合作者，将使用这种尖端的仪器，以推进金属同位素如何跟踪和记录化学，地质和生物过程发生在自然界的理解。这一认识反过来又将使金属同位素地球化学应用于一系列重要问题，包括与污染物金属归宿和迁移、自然沃茨和沉积物中生物必需金属的可用性、矿床的起源以及地球和其他行星上早期生命的记录有关的问题。MC-ICP-MS将位于最近完成的多学科科学大楼II，其中还包括一个新建成的专用洁净室，用于实验和样品制备。该仪器与一个完善的、国际公认的气源质谱设施共用空间，从而将该实验室的分析能力扩展到整个周期表。这些设施和部分NSF支持的技术人员的实践培训将有助于培养当前和下一代的年轻科学家。
