Acquisition of an Inductively Coupled Plasma-Atomic Emission Spectrometer for Environmental and Material Sciences at Penn State

电感耦合等离子体原子发射光谱仪是一种灵敏、通用的测量溶液中多种常见元素浓度的仪器。通过提供一种确定浓度水平的有效手段，这种分析工具在研究原始和受污染的岩石、水和废物中的主要元素和微量元素的去向、迁移和反应性方面是不可或缺的。在宾夕法尼亚州立大学(PSU)，电感耦合等离子体原子发射光谱是本科生和研究生研究和培训的重要工具。来自国家科学基金会和能源部的这笔赠款资金将用于购买Perkin-Elmer Optima 5300DV电感耦合等离子体发射光谱系统，总套装成本约为8.7万美元。宾夕法尼亚州立大学将保证运营该设施的永久高级化学家的工资。在本建议书所代表的所有学院内，课程作业均已到位或可供学生使用电感耦合等离子体发射光谱仪进行分析。例如，在地球科学系，据估计，每年约有20-50名学生接触到电感耦合等离子体原子发射光谱实验室，以便对当地的水和土壤进行环境分析。此外，来自PSU各学术部门和其他大学的每年多达50名用户在许多研究或班级项目中使用该仪器，每年约1100个小时。这种仪器的使用将鼓励和促进PSU教职员工在环境和材料研究领域的许多项目，并鼓励来自周围学院和大学的教职员工进行研究。

The inductively coupled plasma atomic emission spectrometer (ICP-AES) is a sensitive and versatile instrument for measuring the concentration of many common elements in solution. By providing an efficient means of determining levels of concentration, this analytical tool is indispensable in studying the fate, transport, and reactivity of major and trace elements in pristine and contaminated rocks, waters, and wastes. At Penn State (PSU), ICP-AES is an important instrument for research and training for undergraduate and graduate students. Funds from this grant from both the National Science Foundation and the Department of Energy will be used to purchase a Perkin-Elmer Optima 5300 DV ICP-AES system for a total package cost of about $87,000. Penn State will guarantee the salary of the permanent senior chemist to run the facility. Within all Colleges represented in this proposal, coursework is in place or accessible for introduction of students to analysis using ICP-AES. For example, in the Department of Geosciences, it is estimated that approximately 20-50 students per year are exposed to the ICP-AES laboratory for environmental analysis of waters and soils from the local area. Additionally, up to 50 users per year from various PSU academic departments and other universities make use of this instrumentation in a number of research or class projects, for approximately 1100 hours/year. The availability of such an instrument will encourage and stimulate many projects in the area of environmental and materials studies among PSU faculty, and also encourage research by faculty from surrounding colleges and universities.
