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奖励资助的多策略对电感耦合等离子体质谱仪（MC-ICP-MS），使印第安纳大学的科学家团队能够研究金属同位素分馏效应，以及在各种环境，生物，地理和星球上的各种环境，生物，地理和星球上的金属同位素分馏的化学机制。地质科学，化学和公共与环境事务学院的本科，毕业生，博士后和教师研究人员以及附近两个的合作者（主要是本科机构（印第安纳州立大学和Depauw大学），将使用这种尖端的仪器来推动对金属一样的生物学和记录化学物质和记录化学物质和记录的方法，以提高这种态度的化学和记录。这种理解反过来又将使金属同位素地球化学应用于广泛的重要问题，包括与污染物金属命运和运输有关的问题，自然水和沉积物中生物质量金属的可用性，矿床的起源，以及地球和其他行星的早期生命的记录。 MC-ICP-MS将位于最近完成的多学科科学大楼II中，该大楼还包含一个新建的专用清洁室进行实验和样品准备。该仪器与建立良好且具有国际公认的气体质谱设施的空间共享空间，因此将该实验室的分析能力扩展到整个元素周期表中。部分NSF支持的技术人员的这些设施和动手培训将有助于准备当前和下一代的年轻科学家。
