Acquisition of an Inductively Coupled Plasma Mass Spectrometer

为在杜克大学建立一个电感耦合等离子质谱仪(电感耦合等离子质谱仪)设施，需要9601711克莱因资金。电感耦合等离子体质谱是分析各种地质样品中痕量元素，特别是低丰度元素的理想仪器。ICPMS将作为一个多用户设施运行，杜克大学和北卡罗来纳大学教堂山分校(UNC-CH)已承诺提供相应的资金。杜克大学地质部还承诺提供资金，用于一名技术人员的长期支持，以维护仪器，帮助用户获得分析。电感耦合等离子体质谱仪能够在高样品吞吐量下以高精度测量多种元素，因此被认为是分析仪器方面的一项重大进步。目前在岩石样品中常规测量的元素包括稀土元素、高场强元素、重碱元素、铀、钍和铅。该设施将在研究三角地区的几乎所有地球化学和环境研究领域扩大分析能力，并将补充杜克大学和北卡罗来纳大学教堂山分校(UNC-CH)的现有分析设施。该设施将为研究三角地区的一大批多样化的教职员工和学生提供服务，包括火成岩和变质岩石学家、海洋沉积物和微化石地球化学家以及环境(土壤和水)地球化学家。教师在资金和研究生产力方面有着良好的记录，我们地区显然需要一种电感耦合等离子体质谱(ICP-MS)。事实上，我们许多潜在用户的研究已经依赖于在全国各地的远程设施获取电感耦合等离子体质谱数据，而收购杜克大学的电感耦合等离子体质谱设施将使其他人能够探索超出我们目前分析能力范围的新研究途径。此外，我们非常希望我们的众多研究生能够轻松获得他们研究所需的分析设备，以便他们能够熟练地使用分析设备。最后，由于我们杜克大学和北卡罗来纳大学CH分校致力于培养本科生并鼓励他们选择地球科学领域的职业，因此这些聪明的年轻学生有机会利用最先进的分析设备参与研究至关重要。***

9601711 Klein Funds are requested to establish an inductively coupled plasma-mass spectrometer (ICP-MS) facility at Duke University. The ICP-MS is an ideal instrument for the analysis of trace elements, particularly low-abundance trace elements, in diverse geological samples. The ICP-MS will be operated as a multi-user facility and matching funds have been committed from Duke University and the University of North Carolina at Chapel Hill (UNC-CH). The Duke Department of Geology has also committed funds toward the long-term support of a technician to maintain the instrument assist users in obtaining analyses. The ICP-MS is capable of measuring a wide range of elements with high precision at high sample throughput and, as a result, is being recognized as a major advance in analytical instrumentation. Elements now routinely measured in rock samples include the rare earth elements, high field strength elements, heavy alkali elements, U, Th, and Pb. The facility will expand analytical capabilities in virtually every areas of geochemical and environmental research in the Research Triangle are, and will complement existing analytical facilities at Duke and the University of North Carolina-Chapel Hill (UNC-CH). The facility will serve a large and diverse group of faculty and students in the Research Triangle area, including igneous and metamorphic petrologists, marine sediment and microfossil geochemists, and environmental (soil and water) geochemists. The faculty have a well- established record of funding and research productivity, and there is a clear need for an ICP-MS in our area. Indeed, the research of many of our potential users already depends upon the acquisition of ICP-MS data at distant facilities across the country, and the acquisition of an ICP-MS facility at Duke will allow others to explore new avenues of research beyond the reach of our present analytical capabilities. Furthermore, it is highly desirable that our numerous graduate students have easy access to the analytical equipment required for their research so that they can become well-versed in its use. Lastly, because we at Duke and UNC-CH are committed to educating undergraduates and encouraging them to choose careers in the geosciences, it is critical that these bright young students have the opportunity to become involved in research using state-of - art analytical equipment. ***
