This award will fund the refurbishment/upgrade of a 21-year-old Thermo Element 2 ICP-MS instrument in the Plasma Laboratory in the Department of Geology, University of Maryland. It will also fund the acquisition of a laser ablation system (LA). The system upgrade will include replacement of the software and some electronic and vacuum components, making the system compatible with modern versions of the same instrument and thus serviceable. This instrument upgrade in combination with the new laser ablation system will continue the 21-year record of research and education in the Plasma Laboratory. This support will permit the laboratory to continue to address current NSF-sponsored research, as well as serve future research and educational needs. This laboratory has, and will maintain, a rich and diverse portfolio of research programs with these instruments that covers topics spanning from the Earth’s core and mantle to the crust, surface processes, and ocean-atmospheric interactions. Over its 21-year history, the Plasma Laboratory has employed and supervised 38 undergraduate research assistants, provided hands-on experience acquiring geochemical data for 28 senior thesis research projects, and has been a teaching facility used to train students (~53 graduate, ~63 undergraduate, 6 high school) and numerous post-docs on analytical methods. A number of these users have gone on to establish and run their own research laboratories. The laboratory contributions to fundamental knowledge, and those of our “offspring” scientists, have significantly enhanced society’s base of fundamental and applied knowledge of geological and non-geological processes.This facility we will be critical to the analysis of samples used to understand: (1) the compositional nature and origin of the bulk silicate Earth, core, continental crust, and modern mantle, (2) tracing fluid-rock interactions during metamorphism and estimating pressure-temperature-time conditions during metamorphism, (3) volatile cycling on planets and planetesimals, including the Earth, Moon and Mars and their precursor planetesimals, (4) isotope dilution measurements of highly siderophile elements, (5) analysis of forensic materials (including historic poisoning cases and nuclear materials), dinosaur bones, new pharmaceutical materials (including drug delivery systems), superconductors, and next generation batteries, (6) tracing the evolution of the redox state of the Earth’s mantle, (7) controls on volcano explosivity, the generation and evolution of planetary atmospheres, and the storage and transport of volatiles in planetary interiors, and (8) chromatographic column calibrations and improving yields for high-precision isotopic measurements.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项将资助马里兰大学地质系等离子体实验室中已有 21 年历史的 Thermo Element 2 ICP-MS 仪器的翻新/升级。 它还将资助购买激光烧蚀系统（LA）。系统升级将包括更换软件以及一些电子和真空组件，使系统与同一仪器的现代版本兼容，从而可以使用。此次仪器升级与新型激光烧蚀系统相结合，将延续等离子体实验室 21 年的研究和教育记录。这种支持将使实验室能够继续解决当前 NSF 资助的研究，并满足未来的研究和教育需求。该实验室已经并将使用这些仪器维持丰富多样的研究项目组合，涵盖从地核和地幔到地壳、表面过程和海洋-大气相互作用的主题。在其 21 年的历史中，等离子体实验室已雇用和指导了 38 名本科生研究助理，为 28 个高级论文研究项目提供了获取地球化学数据的实践经验，并且一直是用于培训学生（约 53 名研究生、约 63 名本科生、6 名高中生）和众多分析方法博士后的教学设施。其中许多用户已经建立并运行了自己的研究实验室。实验室以及我们“后代”科学家对基础知识的贡献显着增强了社会对地质和非地质过程的基础和应用知识的基础。该设施对于分析用于了解以下内容的样品至关重要：(1) 块状硅酸盐地球、地核、大陆地壳和现代地幔的成分性质和起源，(2) 追踪变质作用期间的流体-岩石相互作用 并估计变质过程中的压力-温度-时间条件，(3) 行星和星子上的挥发性循环，包括地球、月球和火星及其前体星子，(4) 高亲铁元素的同位素稀释测量，(5) 法医材料（包括历史中毒案例和核材料）、恐龙骨骼、新制药材料（包括药物输送系统）的分析， 超导体和下一代电池，(6) 追踪地幔氧化还原态的演变，(7) 控制火山爆发、行星大气的生成和演化以及行星内部挥发物的储存和运输，以及 (8) 色谱柱校准和提高高精度同位素测量的产量。该奖项反映了 NSF 的法定 使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
