Inductively Coupled Plasma Mass Spectrometry (ICP-MS) is a technique which allows users to measure concentrations of rare elements with superior sensitivity. With many applications in a wide range of scientific fields, this fast, multi-element technique has become an indispensable tool in trace elemental analysis. This award will be used to establish an ICP-MS at Black Hills State University (BHSU) that will provide high sensitivity analysis capabilities for researchers in South Dakota and surrounding areas. The ICP-MS will be used by researchers in many disciplines including Physics, Chemistry, Geology, and Engineering. Undergraduate students will be involved in sample preparation, operation, instrument maintenance, and data analysis. This will expand BHSU's program of undergraduate research in the Black Hills region and throughout the state of South Dakota and increase the exposure of undergraduate students to state-of-the-art instrumentation. ICP-MS labs and training will be incorporated into Analytical Chemistry, Instrumental Analysis, Hydrogeology, Volcanology, Mineralogy and Petrology classes serving a combined estimated 90 students per year. BHSU's close proximity to six of the nine Indian reservations in South Dakota results in a large enrollment of American Indian students, many of whom will benefit from the acquisition of the ICP-MS.With this ICP-MS, BHSU will be capable of screening the radio-purity of materials used in rare-event physics experiments at the Sanford Underground Research Facility (SURF). The ICP-MS facility will also be used in support of SURF projects by characterizing the germanium crystals grown at the University of South Dakota and at the South Dakota School of Mines and Technology, and in the study of ancient metamorphosed basalts in and near SURF. Additional geological applications include petrogenesis studies of volcanic and metavolcanic rocks, paleoenvironmental analyses, research of biotic responses to past climate change and analyses of the incorporation and impact of trace metals and organic compounds derived from the Deepwater Horizon oil spill on coastal molluscan species in the Gulf of Mexico. Assessing the toxicity of nanomaterials for renewable energy generation, evaluating lanthanide dopant concentration in upconversion nanomaterials and the determination of complex ferrite compositions and impurities in attrition milled and surface functionalized metallic and intermetallic nanopowders are among the chemistry applications.

电感耦合等离子体质谱（ICP-MS）是一种允许用户以上级灵敏度测量稀有元素浓度的技术。 随着在科学领域的广泛应用，这种快速、多元素的技术已成为痕量元素分析中不可或缺的工具。 该奖项将用于在黑山州立大学（BHSU）建立ICP-MS，为南达科他州及周边地区的研究人员提供高灵敏度分析能力。 ICP-MS将被许多学科的研究人员使用，包括物理，化学，地质和工程。 本科生将参与样品制备，操作，仪器维护和数据分析。这将扩大BHSU在黑山地区和整个南达科他州的本科研究计划，并增加本科生接触最先进的仪器。 ICP-MS实验室和培训将纳入分析化学，仪器分析，水文地质学，火山学，矿物学和岩石学课程，每年为90名学生提供服务。在南达科他州的九个印第安人保留区中，BHSU靠近六个印第安人保留区，这导致大量的美国印第安学生入学，其中许多人将受益于ICP-MS的收购。有了这个ICP-MS，BHSU将能够在桑福德地下研究设施（SURF）筛选稀有事件物理实验中使用的材料的放射性纯度。ICP-MS设施还将用于支持SURF项目，对南达科他州大学和南达科他州矿业与技术学院生长的锗晶体进行表征，并用于研究SURF及其附近的古代变质玄武岩。其他地质应用包括火山岩和变质火山岩的岩石成因研究、古环境分析、生物对过去气候变化的反应研究，以及分析从“深水地平线”漏油事件中提取的微量金属和有机化合物对墨西哥湾沿海软体动物物种的结合和影响。评估用于可再生能源发电的纳米材料的毒性，评估上转换纳米材料中的镧系元素掺杂剂浓度，以及确定研磨和表面官能化金属和金属间化合物纳米粉末中的复杂铁氧体成分和杂质是化学应用之一。
