Acquisition of a sector magnet ICP-MS for Ocean and Earth Science Research at Florida State University

该合同将向佛罗里达州立大学提供25万美元，用于购买扇形磁感应耦合等离子体质谱计（SM-ICP-MS）。这台仪器将取代几个地球科学研究人员使用的通用设备中已有14年历史的ELEMENT1。制造商不再支持该仪器的维修，备件也很稀缺。在过去的几年中，由于越来越频繁的部件故障，该仪器出现了严重的停机时间。佛罗里达州立大学将以25万美元的金额与国家科学基金会的捐款相匹配，总预算为50万美元。FSU还以国家资助的技术地位支持ICP-MS设施。新工具将支持各种资助项目。FSU的几个正在进行的研究项目严重依赖于内部最先进的ICP-MS能力的可用性，特别是：(1)海洋铁循环与全球碳循环的关系的研究；(2)海洋气溶胶中痕量金属沉积研究；(3)全球汞循环研究；以及地幔和地壳的地球化学动力学。更广泛的影响：国家强磁场实验室的地球化学项目支持研究生（目前12人）和博士后（3人）在他们的研究中使用该仪器。对于CLIVAR和GEOTRACES等大型研究项目来说，该仪器是必不可少的。除了主要pi及其学生和博士后的研究外，该仪器还将为地球海洋与大气科学系的其他教师、化学系的教师、NHMFL和外外用户的研究做出贡献。

This award will provide $250,000 to the Florida State University for the acquisition of a sector magnet inductively coupled plasma mass spectrometer (SM-ICP-MS). This instrument will replace a 14-year-old ELEMENT1 in a common facility used by several earth science researchers. The manufacturer does not support service on that instrument anymore and spare parts are scarce. The instrument over the last few years has seen significant downtime due to more and more frequent breakdown of components. FSU will match the NSF contribution at the amount of $250,000 for a total budget of $500,000. FSU also supports this ICP-MS facility with a state-funded technical position. The new instrument will support a variety of funded projects. Several ongoing research programs at FSU are critically dependent upon the availability of in-house state-of-the-art ICP-MS capability, especially: (1) studies of iron cycling in the ocean in relation to global carbon cycling; (2) studies of aerosolized trace metal deposition in the sea; (3) studies of the global mercury cycle; and geochemical dynamics of the Earth's mantle and crust.BROADER IMPACTS: The Geochemistry Program of the National High Magnetic Field Laboratory supports graduate students (12 present) and post-docs (3) that will use this instrument in their research. The instrument is essential for projects that are part of larger scale research programs such as CLIVAR and GEOTRACES. Apart from the research of the primary PIs and their students and post-docs, the instrument will contribute to the research of other faculty in the Department of Earth Ocean and Atmospheric Sciences, as well as faculty of the Department of Chemistry, the NHMFL and users outside FSU.
