EAR-00521201SaltersThis award, made through the Major Research Instrumentation (MRI) Program, provides partial support for the purchase of a Multicollector Inductively Coupled Plasma Mass Spectrometer (MC-ICP-MS), and associated hardware. The instrument will be housed in a new Plasma Analytical Facility (PAF) at the National High Magnetic Field Laboratory (NHMFL). We will use the instrument for:- mantle geochemistry to constrain the processes that result in mantle heterogeneity as the instrument allows improved analyses of Hf and Pb isotopes as well as in-situ trace element analyses;- cosmochemistry by measurement of heavy elemental abundances in extra terrestrial materials. returned from the GENESIS and STARDUST missions. For this project the MC-ICP-MS will be coupled with a single collector instrument for the determination of the major elements. - low temperature geochemistry where the MC-ICP-MS allows metal stable isotope analysis. Foremost will be Fe-isotope analyses to investigate the cycling of Fe in the oceans. The MC-ICP-MS will be instrumental in our development of a Biogeochemical Dynamics Program, an interdisciplinary program that will focus on the interplay between chemistry and biology in aquatic ecosystems and which will make use of the unique instrumentation at the NHMFL. We will develop the protocols to measure the isotopic composition of environmentally significant metals like Cu, Zn, Mo and Hg. At the NHMFL the instrument will also be of use to the material science and condensed matter physics faculty.

Salters-00521201该奖项通过重大研究仪器（MRI）计划颁发，为购买多接收器电感耦合等离子体质谱仪（MC-ICP-MS）和相关硬件提供部分支持。 该仪器将被安置在国家高磁场实验室（NHMFL）的新血浆分析设施（PAF）中。 我们将使用该仪器：-地幔地球化学，以限制的过程，导致地幔的异质性，因为该仪器允许改进的Hf和Pb同位素分析，以及原位微量元素分析;-宇宙化学的测量重元素丰度在地球外的材料。从创世纪和星尘任务返回。 对于本项目，MC-ICP-MS将与单个收集器仪器相结合，用于测定主要元素。 - 低温地球化学，其中MC-ICP-MS允许进行金属稳定同位素分析。 首先将进行铁同位素分析，以调查海洋中铁的循环。 MC-ICP-MS将有助于我们开发生物地球化学动力学计划，这是一个跨学科的计划，将侧重于水生生态系统中化学和生物学之间的相互作用，并将利用NHMFL独特的仪器。我们将制定协议，以测量环境重要金属，如铜，锌，钼和汞的同位素组成。在NHMFL，该仪器也将用于材料科学和凝聚态物理系。
