Acquisition of an inductively-coupled plasma mass spectrometer

该奖项是根据2009年美国复苏和再投资法案（公法111 - 5）资助的。 该奖项将资助华盛顿州立大学（WSU）地质分析实验室购买和安装一台新的电感耦合等离子体质谱仪（ICPMS）仪器。 它将取代一个已经过时的12年前的仪器。在WSU的ICPMS设施是在非常广泛的地球和环境科学和化学研究。 使用该仪器数据的内部项目包括研究火山口（新墨西哥州杰梅斯山的瓦勒斯火山口）和大型火成岩省（哥伦比亚河洪水玄武岩和蛇河平原流纹岩）的超级喷发。 在这些情况下，微量元素数据是必不可少的，以了解产生，存储和运输的岩浆，饲料最大的玄武岩和流纹岩喷发，这是已知的，在过去造成重大的环境破坏。 一个非常不同的内部应用是研究水地球化学、基础溶液化学和镧系元素和锕系元素的分离科学，并应用于放射性废物的运输和储存以及核燃料循环的最终关闭。 在更广泛的美国科学界，WSU分析服务以低成本向北美（以及一些海外）的广大大学和机构科学家提供高质量的数据，这些科学家研究岩石、沉积物、土壤和水的微量元素含量。沃茨并开始依赖WSU实验室提供的服务。 该设施还将用于培训未来的分析师和地球化学家，他们将进入地球科学/环境科学工作队伍。 每年约有12名来自WSU和其他地方的研究生接受样品制备、实验设计和ICPMS设备使用方面的培训。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). This award will fund acquisition and installation of a new inductively coupled plasma mass spectrometer (ICPMS) instrument in the GeoAnalytical Lab at Washington State University (WSU). It will replace a 12 year old instrument that is now obsolete. The ICPMS facility at WSU is employed in a very broad range of Earth and enviromental science and chemistry research. In-house projects that use data from the instrument include studies of super-eruptions from volcanic calderas (Valles caldera, Jemez Mountains, NM) and large igneous provinces (Columbia River flood basalts and Snake River Plain rhyolites). In these cases, trace element data are essential to understanding the generation, storage, and transport of magmas that feed the largest basaltic and rhyolitic eruptions, which are known to have caused major environmental disruption in the past. A very different in-house application is investigation of the aqueous geochemistry, basic solution chemistry and separation science of lanthanides and actinides with applications to radioactive waste transport and storage and to the ultimate closing of the nuclear fuel cycle. In the broader U.S. scientific community, the WSU analytical service supplies high-quality data at low cost to a wide range of university- and institution-based scientists in North America (and some overseas) who work with the trace element contents of rocks, sediments, soils and waters and have come to rely on the service provided by the WSU laboratory. The facility will also serve to train future analysts and geochemists who will enter the geoscience/enviromental science workforce. About 12 graduate students per year from WSU and elsewhere are trained in sample preparation, experiment design, and use of the ICPMS equipment.
