Acquisition of an Inductively Coupled Plasma Mass Spectrometer

小行星9601711 请求提供资金在杜克大学建立一个电感耦合等离子体质谱仪设施。ICP-MS是分析各种地质样品中微量元素，特别是低丰度微量元素的理想仪器。 ICP-MS将作为一个多用户设施运行，杜克大学和查佩尔山的北卡罗来纳州大学（UNC-CH）已承诺提供配套资金。 杜克地质系还承诺提供资金，用于长期支持技术人员维护仪器，协助用户进行分析。 ICP-MS能够在高样品通量下以高精度测量各种元素，因此被认为是分析仪器的重大进步。 现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、U、Th和Pb。 该设施将扩大研究三角区几乎所有地球化学和环境研究领域的分析能力，并将补充杜克和北卡罗来纳大学教堂山分校（UNC-CH）的现有分析设施。 该设施将为三角研究区的大量不同的教师和学生提供服务，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。 该学院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ICP-MS。 事实上，我们的许多潜在用户的研究已经依赖于在全国各地的远程设施的ICP-MS数据的获取，而在杜克获得ICP-MS设施将允许其他人探索我们目前分析能力所无法达到的新的研究途径。 此外，我们非常希望 许多研究生都很容易获得他们研究所需的分析设备，以便他们能够熟练地使用这些设备。 最后，因为我们在杜克和UNC-CH致力于教育本科生，并鼓励他们选择在地球科学的职业生涯，这是至关重要的，这些聪明的年轻学生有机会成为参与研究使用国家的最先进的分析设备。 ***

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. ***
