Enhancing the Roanoke College Curriculum with an Atomic Absorption Spectrometer

环境分析在罗阿诺克学院变得越来越重要，这既是因为环境科学课程的引入，也是因为在整个课程中广泛使用了基于多周应用程序的项目。这一新的重点产生了对金属痕量分析的需求，将使用火焰/熔炉原子吸收光谱仪来满足这一需求。新的仪器功能包括改进的炉法检测极限，背景校正能力，以及用于火焰分析的更高温度燃烧器。新的实验和研究项目将在为期四年的仪器综合培训课程的背景下制定。将使用多层次的仪器经验序列来教育学生基本操作、先进技术和基本原理。有趣的实验将包括空气、水和土壤分析、法医调查和统计设计的优化。新的环境科学计划还创造了各种本科生研究机会，对这些机会来说，痕量金属分析的可用性是至关重要的。外联活动将是该项目的一个组成部分。为期多年的乐器工作坊将向一大批中学教师和学生介绍先进的现代乐器。工作坊将强调基本原理、深入的实际操作仪器体验和实际应用。此外，新的光谱仪将广泛用于高中生的研究。

Environmental analyses have become increasingly important at Roanoke College, due both to the introduction of an Environmental Science program and to extensive use of multi-week applications based projects throughout the curriculum. This new emphasis has created a need for trace analysis of metals, which will be met using a combination flame/furnace atomic absorption spectrometer. The new instrumental features include the improved detection limits of the furnace method, background correction capabilities, and a higher temperature burner for flame analyses. New experiments and research projects will be developed in the context of a comprehensive four year instrumentation training curriculum. A multi-level sequence of instrument experiences will be used to educate students on basic operations, advanced techniques, and fundamental principles. Interesting experiments will include air, water, and soil analyses, forensic investigations, and a statistically designed optimization. The new Environmental Science program is also creating a variety of undergraduate student research opportunities for which the availability of trace metal analysis is critical. Outreach activities will be an integral part of this project. A multi-year series of instrumentation workshops will introduce advanced modern instrumentation to a large group of secondary level teachers and students. Workshops will emphasize basic principles, in-depth hands-on instrument experience, and real life applications. Additionally, the new spectrometer will be extensively used for high school student research.
