MITERAC shall expand the research endeavors of 18 researchers from 6 universities in Indiana and Michigan. This will be accomplished via the acquisition of the following new instruments with funding from the MRI Program, which will be combined with the existing high resolution Element 2 ICP-MS (with 213 nm laser ablation unit and liquid chromatographic system): multiple collector-inductively coupled plasma mass spectrometer (MC-ICP-MS), 193 nm laser ablation and microdrilling systems, and dedicated Hg analyzers. The MC-ICP-MS instrumentation shall provide researchers the capacity to obtain highly precise and accurate isotope data from various types of environmental and geological samples. The 193 nm laser system and microdrill shall be used to acquire high quality, isotope data at high spatial resolution; i.e. 10s to 100s of micron scale from geological and archaeological samples. The Hg analyzers shall be used to quantify mercury levels in environmental samples as part of on-going research investigations in pollution remediation.MITERAC shall be a facility specializing in isotope geochemistry and trace element research; one that is fully accessible to undergraduates and graduate students, and faculty. The establishment of MITERAC will provide both graduate and undergraduate students from 6 universities with experience in handling and interpretation of isotope data, and critical hands-on training and expertise at Notre Dame in latest ICP-MS technology and highly innovative instrumentation; training that is critical to their scientific development. The facility will address research covering a broad range of research disciplines, including petrology, planetary geology, anthropology, the environment, engineering (pollutant remediation), nuclear forensics, geomicrobiology, and hydrology; the latter research areas having a direct impact on societal issues. Our proposed facility shall attract scientists/engineers and accompanying students from around the world to conduct their highly innovative research, which ultimately enhances the educational experiences of all involved.

MITERAC 将扩大来自印第安纳州和密歇根州 6 所大学的 18 名研究人员的研究工作。这将通过 MRI 计划的资助购买以下新仪器来实现，这些仪器将与现有的高分辨率 Element 2 ICP-MS（带有 213 nm 激光烧蚀装置和液相色谱系统）相结合： 多个感应收集器耦合等离子体质谱仪 (MC-ICP-MS)、193 nm 激光烧蚀和微钻孔系统以及专用汞分析仪。 MC-ICP-MS 仪器应使研究人员能够从各种类型的环境和地质样品中获取高精度和准确的同位素数据。 193 nm激光系统和微钻将用于获取高空间分辨率的高质量同位素数据；即来自地质和考古样本的 10 到 100 微米级。汞分析仪应用于量化环境样品中的汞含量，作为正在进行的污染修复研究调查的一部分。MITERAC 应是一家专门从事同位素地球化学和微量元素研究的设施；本科生、研究生和教师完全可以使用的一种方法。 MITERAC 的成立将为来自 6 所大学的研究生和本科生提供处理和解释同位素数据的经验，以及圣母大学最新 ICP-MS 技术和高度创新仪器方面的关键实践培训和专业知识；对他们的科学发展至关重要的培训。该设施将开展涵盖广泛研究学科的研究，包括岩石学、行星地质学、人类学、环境、工程（污染物修复）、核法证学、地球微生物学和水文学；后者的研究领域对社会问题有直接影响。我们提议的设施将吸引来自世界各地的科学家/工程师和随行学生进行高度创新的研究，最终增强所有参与者的教育体验。
