Acquisition of a High Resolution, Magnetic Sector Inductively Coupled Plasma Mass Spectrometry (ICP-MS) Facility for the University of Notre Dame.

圣母大学四极ICP-MS已经运行了11年，并在各种材料的微量元素分析方面取得了卓越的声誉。该提案要求资金升级该设施，包括购买高分辨率磁扇区ICP- ms (ELEMENT2)， 213 nm激光烧蚀装置，离子色谱仪，自动取样能力，低流量样品导入装置，双α光谱仪，以及对ICP废气进行hepa过滤，以便分析低放射性样品。新设施将由一名全职的大学聘用的实验室经理监督，他已经在ICP分析技术方面拥有超过15年的经验。新设施将显著扩大印第安纳州圣母大学及周边各州的研究能力。该提案的理由是，正在进行的研究项目已经进展到现在所需的分析超出了四极ICP-MS的能力，266 nm激光烧蚀装置不能提供准确的深度轮廓（凹坑不是平底的），小于~25微米的凹坑是不可能的，并且没有能力进行物种形成或“低流量”研究。等待使用新设施的研究项目包括富锕系放射性废物的稳定、锕系元素和钪的植物修复、地下水的化学输入、催化转炉产生的铂族元素（PGE）污染、月球演化、柱状玄武岩中的PGE、类地行星的晚期饰面研究、酸性矿山排放、地球微生物学、生物地球化学风化、重金属的生物可利用性、癌症研究、膳食补充剂/草药中的有毒金属、晶体地层学、西南太平洋的构造-热演化、高山盆地的元素流动性和物种形成研究。新设施将加强圣母大学新环境分子科学研究所的推广工作，该研究所已经为高中三年级学生启动了一个少数民族夏季研究项目，并为代表性不足的学生启动了一个REU项目。相对较新的地球科学研究生课程（1994年开始）继续发展，重点放在让研究生利用新的ICP-MS设备作为他们研究的一部分。我们计划使用旧的四极ICP-MS作为本科生和研究生的教学设备。在2-3年内，我们希望扩大这一范围，使PQII成为科学和工程专业顶尖分析课程的基石。

EAR-0321161NealThe University of Notre Dame quadrupole ICP-MS has been in operation for 11 years and has developed a reputation for excellence in trace element analysis of a variety of materials. This proposal requests funds to upgrade this facility with the purchase a high-resolution magnetic sector field ICP-MS (ELEMENT2), a 213 nm laser ablation unit, an ion chromatograph, autosampling capabilities, a low flow sample introduction apparatus, a dual alpha spectrometer, and HEPA-filtration of the ICP exhaust so low-level radioactive samples can be analyzed. The new facility will be overseen by a full time, university employed laboratory manager already in place who has over 15 years of experience in ICP analytical techniques. The new facility will significantly expand the research capabilities at Notre Dame, in Indiana, and the surrounding states. The justification for this proposal is that research projects being conducted have progressed to the point where the analyses now required are beyond the capabilities of a quadrupole ICP-MS, the 266 nm laser ablation unit does not give accurate depth profiles (pits are not flat bottomed) and pits smaller than ~25 micrometers are not possible, and there is no capability for speciation or "low-flow" studies. Research projects waiting to use the new facility include Stabilization of Actinide-Rich Radioactive Waste, Phytoremediation of Actinides & Sc, Chemical Inputs to Groundwater, Platinum-Group Element (PGE) Pollution from Catalytic Converters, Lunar Evolution, PGEs in Plume-Derived Basalts, Late Veneer Studies of the Terrestrial Planets, Acid Mine Drainage, Geomicrobiology, Biogeochemical Weathering, Bioavailability of Heavy Metals, Cancer Research, Toxic Metals in Dietary Supplements/Herbal Medicines, Crystal Stratigraphy, Tectonothermal Evolution of the SW Pacific, Element Mobility in Alpine Basins, and Speciation Studies. The new facility will enhance the outreach efforts of the new Environmental Molecular Science Institute at Notre Dame, which has initiated a minority summer research program for high school juniors and a REU program for under-rep-resented students. The relatively new graduate program in the geosciences (est. 1994) continues to grow and emphasis is placed upon getting graduate students to make use of the new ICP-MS facility as part of their research. We plan to use the old quadrupole ICP-MS as a teaching facility for undergraduate and graduate students. Within 2-3 years, we hope to expand this to make the PQII the cornerstone of a capstone analytical course for science and engineering majors.
