MRI: Acquisition of a Multi-Collector Inductively Coupled Plasma Mass Spectrometer (MC-ICP-MS) for isotopic studies in earth and environmental studies

该奖项为俄勒冈州立大学(OSU)购买新的多收集器电感耦合等离子体质谱(MC-ICP-MS)仪器提供资金，以支持地球和环境科学的尖端研究。购买最新一代的MC-ICPMS将立即对俄亥俄州立大学和太平洋西北部的教职员工的研究产生广泛的影响。所支持的研究活动对太平洋西北和其他地区的居民具有重大的社会影响，包括对气候变化、临界区进程、人为污染、自然灾害和渔业管理的研究。此次收购将提高地球、海洋和大气科学学院和农业科学学院(OSU)培养高技能毕业生的能力，为在各种环境下的职业生涯做好准备。本科生和研究生的教育和研究将通过设施参观和仪器演示、课堂项目、学生研究项目和课程练习来支持。新的MC-ICP-MS提供的分析能力将使俄亥俄州立大学在快速发展的高影响力研究领域保持领先地位。仅在过去的5年里，质谱仪设计中的分析改进继续以越来越高的灵敏度推动精密度和准确度的界限。这些改进将开辟许多新的研究途径，减少所需的样品材料数量，提高所有应用的采样分辨率，消除干扰，并通过同时收集更多的同位素。即将由MC-ICP-MS支助的项目的具体例子包括：开发重稳定同位素，作为环境应用的工具(例如，检测和量化受污染地下水中铀的清除情况；追踪有色金属冶炼排放)；了解关键区过程(包括追踪土壤投入的来源，研究气候、侵蚀和风化之间的关系)；激光烧蚀，以高空间分辨率测量同位素组成；以及气候变化(包括追踪过去的海洋循环和重建过去的海洋营养物质分布)。

This award provides funding for the acquisition of a new Multi-Collector Inductively Coupled Plasma Mass Spectrometer (MC-ICP-MS) instrument to support cutting-edge research in the earth and environmental sciences at Oregon State University (OSU). The acquisition of a latest generation MC-ICP-MS will have an immediate broad impact on the research of faculty at OSU and in the Pacific Northwest. Supported research activities have strong societal implications for the residents of the Pacific Northwest and elsewhere including studies of climate change, critical zone processes, anthropogenic pollution, natural hazards, and fisheries management. The acquisition will improve the ability of the College of Earth, Ocean, and Atmospheric Sciences and the College of Agricultural Sciences (OSU) to produce highly skilled graduates prepared for careers in a range of settings. Undergraduate and graduate education and research will be supported through facility tours and instrument demonstrations, class projects, student research projects, and course exercises.The analytical capability enabled by the new MC-ICP-MS will position OSU to remain at the forefront of rapidly developing high impact research areas. In just the past 5 years, analytical improvements in the design of mass spectrometers continue to push the boundaries of precision and accuracy at higher and higher sensitivities. These improvements will open up many new avenues of research by reducing the amount of sample material needed, improving the sampling resolution for all applications, removing interferences, and through the simultaneous collection of a larger number of isotopes. Specific examples of projects imminently proposed that will be supported by the MC-ICP-MS include: developing heavy stable isotopes as tools in environmental applications (e.g., detecting and quantifying uranium removal from contaminated groundwater; tracing non-ferrous metal smelting emissions); understanding critical zone processes (including tracing sources of soil inputs and examining the relationship between climate, erosion, and weathering); laser ablation measurements of isotopic compositions at high spatial resolution; and climate change (including tracing ocean circulation in the past and reconstructing past ocean nutrient distributions).
