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.

圣母大学四极杆ICP-MS已经运行了11年，在各种材料的痕量元素分析方面享有卓越的声誉。该提案要求提供资金升级该设施，购买高分辨率扇形磁场ICP-MS（ELEMENT 2）、213 nm激光烧蚀装置、离子色谱仪、自动取样能力、低流量进样装置、双α光谱仪和ICP排气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实验室经理监督，他在ICP分析技术方面拥有超过15年的经验。新设施将大大扩大在圣母院，在印第安纳州，和周边国家的研究能力。该提议的理由是，正在进行的研究项目已经发展到现在所需的分析超出了四极ICP-MS的能力，266 nm激光烧蚀装置不能给出准确的深度剖面（凹坑不是平底的），并且不可能有小于~25微米的凹坑，并且没有能力进行形态或“低流量”研究。等待使用新设施的研究项目包括富锕系元素放射性废物的稳定化、锕系元素Sc的植物修复&、地下水的化学输入、催化转化器的铂族元素（PGE）污染、月球演化、羽状玄武岩中的PGE、陆地行星的晚期单板研究、酸性矿井排水、地球微生物学、生物地球化学风化、重金属的生物利用度、癌症研究、膳食补充剂/草药中的有毒金属、晶体地层学、西南太平洋的构造演化、高山盆地中元素的流动性和形态研究。 新设施将加强圣母院新环境分子科学研究所的外联工作，该研究所已启动了一项针对高中三年级学生的少数民族夏季研究计划和一项针对代表不足学生的REU计划。相对较新的研究生课程在地球科学（est。1994年）继续增长，重点放在让研究生利用新的ICP-MS设施作为他们的研究的一部分。我们计划使用旧的四极杆ICP-MS作为本科生和研究生的教学设施。在2-3年内，我们希望扩大这一点，使PQII成为科学和工程专业的顶峰分析课程的基石。
