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学系的等离子实验室中21岁的Thermo Element 2 ICP-MS仪器的翻新/升级。它还将资助对激光消融系统（LA）的收购。系统升级将包括替换软件以及一些电子和真空组件，使该系统与同一仪器的现代版本兼容，因此可以使用。该仪器升级与新的激光消融系统结合使用，将继续在血浆实验室的研究和教育记录21年。这种支持将使实验室能够继续解决当前的NSF赞助研究，并满足未来的研究和教育需求。该实验室已经并且将使用这些工具来维持丰富而多样化的研究计划组合，涵盖了从地球核心和地幔到地壳，表面过程和海洋 - 大气相互作用的主题。在其21年的历史中，血浆实验室已被雇用和监督38位本科研究助理，提供了为28个高级论文研究项目获得地球化学数据的动手经验，并且是用于培训学生的教学设施（约53名毕业生，约63个本科生，6个高中），以及有关分析方法的大量研究。这些用户中的许多用户继续建立并运行自己的研究实验室。实验室对基本知识的贡献以及我们的“后代”科学家的贡献，显着增强了社会对地质和非地质过程的基本和应用知识的基础。我们将对用于理解的样本进行分析至关重要。变质和估计变质过程中的压力温度条件，（3）在行星和行星上的挥发性循环，包括地球，月球和火星及其前体行星及其前体行星，（4）同位素稀释度测量值高度辅助元素的高度辅助元素（包括途径材料）（包括途径材料）（包括途径材料），包括良好的材料（包括良好的材料），餐具（5）系统，超导体和下一代电池，（6）追踪地球地幔的氧化还原状态的演变，（7）控制火山爆炸性，火山爆炸性的控制，行星气氛的产生和演变，行星挥发物的存储和运输以及行星内部融合和（8）高度量的ISOT级别的ISOT级别的ISOT级别的ISOT量，并改善了ISOT级别的ISOT级别，并改善了ISOT级别的ISOT级别，并改善了ISOT级别的ISOT型号。法定使命，并使用基金会的知识分子优点和更广泛的影响标准通过评估被认为是宝贵的支持。
