Acquisition of a Quadrupole Inductively-Coupled Plasma Mass Spectrometer (ICP-MS) for Earth and Related Sciences

0744425 Feineman该提案寻求获得四极杆ICP-MS系统的资金，用于快速分析激光烧蚀材料。该设施目前有一个213纳米激光烧蚀系统与高分辨率磁扇区ICP-MS。一个热X系列II四极ICP-MS的要求，这将增加质量扫描速率（最终的灵敏度）的数量级。配套资金由PI的启动资金和其他PSU设施提供。PSU将保证一名永久分析化学家的工资，以监督该设施。新的ICP-MS将用于区分东非裂谷系熔岩，通过捕虏晶和捕虏体分析限制埃塞俄比亚中部的热结构和岩石圈厚度，分析晶体和硅酸盐液体微量元素扩散，确定东非裂谷系内的岩浆混合和储存，并用于一般实验，以更好地了解矿物和流体，矿物和熔体之间的元素分配，融化物和液体还将支持一些学生项目。该仪器将占用材料表征实验室（MCL）的现有空间，将由一名科学家提供实践培训和认证。专职人员将监督日常操作和维护。PSU为该设施提供一般支持，并提供仪器用户费，以支持维护、用品和维修资金。所要求的工具将是新雇用的女性的职业工具。文书会并入本科吗？法医地球科学？然后呢？环境地球化学技术班该仪器将提供给PSU？科学和工程研究中的女性和少数民族本科生研究经验计划。

0744425FeinemanThis proposal seeks funding to acquire a quadrupole ICP-MS system for rapid analysis of laser ablated material. The facility currently has a 213 nm laser ablation system coupled with high resolution magnetic sector ICP-MS. A Thermo X-Series II quadrupole ICP-MS is requested which will increase the mass scanning rate (ultimately the sensitivity) by an order of magnitude. Matching funds are provided by the PI's startup monies and from other PSU facilities. PSU will guarantee salary for a permanent analytical chemist to oversee the facility. The new ICP-MS will be used in differentiating East African Rift System lavas, in constraining central Ethiopian thermal structure and lithosphere thickness by xenogcrist and xenolith analysis, in analyzing crystal and silicate liquid trace element diffusion, in determining magma mixing and storage within the East African Rift System, and in for general experiments to better understand element partitioning between minerals and fluids, minerals and melts, and melts and fluids. Several student projects will also be supported. The instrument will occupy existing space in the Material Characterization Laboratory (MCL), Hands-on training and certification will be provided by a staff scientist. The dedicated staff will oversee the day-to-day operation and maintenance. PSU provides general support for the facility with instrument user fees supporting maintenance, supplies and repair funds. The requested instrument will be a career vehicle for a new female hire. The instrument will be incorporated into undergraduate ?Forensic Geoscience,? and ?Techniques in Environmental Geochemistry? classes. The instrument will be made available to PSU?s Women in Science and Engineering Research and Minority Undergraduate Research Experiences programs.***
