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

该奖项将为佛罗里达州立大学提供25万美元，用于购买扇形磁铁电感耦合等离子体质谱仪（SM-ICP-MS）。这台仪器将取代一台已有14年历史的ELEMENT 1，该仪器是几位地球科学研究人员使用的一个共同设施。制造商不再支持该仪器的服务，备件也很稀缺。在过去几年中，由于组件故障越来越频繁，该仪器出现了严重的停机时间。FSU将与NSF的捐款相匹配，总预算为25万美元，总预算为50万美元。FSU还支持这个ICP-MS设施与国家资助的技术立场。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）与全球碳循环有关的海洋铁循环研究;（2）海洋中气溶胶痕量金属沉积研究;（3）全球汞循环研究;以及地球地幔和地壳的地球化学动力学研究。国家高磁场实验室的地球化学计划支持研究生（12名）和博士后（3）将在他们的研究中使用这种仪器。该仪器对于CLIVAR和GEOTRACES等大型研究项目的一部分至关重要。除了主要PI及其学生和博士后的研究外，该仪器还将有助于地球海洋和大气科学系其他教师的研究，以及化学系，NHMFL和FSU以外的用户的教师。

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.
