EAR-0447237BodnarThis award will support a full-time technician to maintain and operate equipment in the soon to be established laser ablation ICP-MS laboratory in the Department of Geosciences at Virginia Tech. Funding to establish the LA-ICP-MS laboratory was recently awarded to the PI by the NSF Major Research Instrumentation Program. The instrumentation and operational protocol for the laboratory are designed specifically for analysis of fluid and melt inclusions. A laser ablation ICP-MS laboratory for analysis of fluid and melt inclusions was identified as a highpriority research need during an NSF-sponsored workshop entitled Research Opportunities in the Geology and Geochemistry of Mineral Deposit Systems that was held in Denver, Colorado, in October, 2002. Establishment of a laser ablation ICP-MS laboratory for fluid and melt inclusion analysis has broad support across the geosciences in the U.S., as documented by letters of support from 34 leading researchers from academic and government labs. The system to be installed at Virginia Tech will include a 193 nm ArF excimer laser combined with an ICP-MS. The laser system that best meets the requirements for fluid inclusion analysis is the GeoLas + manufactured by Lambda Physik. This will be coupled to an Agilent Technologies 7500cs ICP-MS. This instrument will be used to determine the major, minor and trace elements in both synthetic and natural fluid and melt inclusions, and will be available to all researchers requiring such data from fluid and melt inclusions.The Department of Geosciences at Virginia Tech maintains a strong commitment to outreach, education and participation of under-represented groups. While not specifically related to this proposal, the laser ablation ICP-MS laboratory will in the future be used in summer programs designed for high school science teachers. This program has operated successfully on the Virginia Tech campus for several years, and will be expanded in future years to include access to a wider range of facilities within the Department of Geosciences. Having a full-time technician dedicated to the laser ablation ICP-MS laboratory will also facilitate access to the lab by graduate students, post doctoral researchers and faculty from other institutions and will contribute in a general way to training of the future professoriate.

EAR-0447237Bodnarthis Award将支持一名全职技术人员，以在即将建立的弗吉尼亚理工学院地球科学系的激光消融ICP-MS实验室中维护和操作设备。 NSF主要研究仪器计划最近将建立LA-ICP-MS实验室的资金授予​​了PI。实验室的仪器和操作方案是专门设计用于分析流体和融合物的。 用于分析流体和熔体包含的激光消融ICP-MS实验室被确定为在NSF赞助的题为“矿物质沉积系统地质和地球化学的研究机会”期间的高级研究需求，该研究机会在2002年10月在科罗拉多州丹佛市举行。美国，由来自学术和政府实验室的34位主要研究人员的支持信所记载。弗吉尼亚理工大学安装的系统将包括193 nm ARF准分子激光与ICP-MS相结合。 最能满足流体纳入分析要求的激光系统是Lambda Physik生产的Geolas +。这将与Agilent Technologies 7500C ICP-MS耦合。该仪器将用于确定合成和天然液体和融化含量的主要，次要和微量元素，并将为所有需要从流体和熔体融合物中进行此类数据提供的研究人员提供。弗吉尼亚州理工学院的地球科学系保持着强有力的承诺，致力于推出，教育和参与不足的小组。虽然与该提案没有特别的关系，但将来将在为高中科学教师设计的夏季计划中使用激光消融ICP-MS实验室。该计划已在弗吉尼亚理工大学的校园成功运营了几年，并将在未来几年进行扩展，以包括在地球科学系内获得更广泛的设施。拥有一名专门用于激光消融ICP-MS实验室的全职技术人员还将促进研究生，博士后研究人员和其他机构的教职员工进入实验室，并将为培训未来教授的一般方式做出贡献。
