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

0744425本提案寻求资金，以获得一个用于激光烧蚀材料快速分析的四极电感耦合等离子体质谱系统。该设施目前拥有213 nm激光消融系统，并配有高分辨率磁扇区电感耦合等离子体质谱仪。需要一台Thermo X系列II四极电感耦合等离子体质谱仪，这将使质量扫描速度(最终提高灵敏度)提高一个数量级。配套资金由PI的启动资金和其他PSU设施提供。PSU将保证一名长期分析化学家的工资，以监督该设施。新的电感耦合等离子体质谱将用于区分东非裂谷系熔岩，通过捕虏岩和捕虏体分析来约束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痕量元素的扩散，确定东非裂谷系内的岩浆混合和储存，以及用于一般实验，以更好地了解矿物和流体、矿物和熔体、熔体和流体之间的元素分配。几个学生项目也将得到支持。该仪器将占用材料表征实验室(MCL)的现有空间，将由一名工作人员科学家提供实际培训和认证。全心全意的工作人员将监督日常运营和维护。PSU为设施提供一般支持，仪器使用费支持维护、供应和维修资金。申请的乐器将是新招聘女性的职业用车。该仪器将被纳入本科、法医地球科学、？和？环境地球化学技术？上课。该仪器将提供给巴黎州立大学S女理工科研究和少数民族本科生研究体验项目。*

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.***
