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.

由于引入环境科学计划以及在整个课程中广泛使用基于应用程序的项目，因此在罗阿诺克学院（Roanoke College）的环境分析变得越来越重要。这种新的重点已经需要对金属进行跟踪分析，该金属将使用组合/炉子原子吸收光谱仪满足。新的仪器功能包括改进的炉子方法的检测极限，背景校正功能以及更高的温度燃烧器进行火焰分析。 新的实验和研究项目将在全面的四年仪器培训课程的背景下开发。多层次的仪器体验将用于教育学生有关基本操作，高级技术和基本原则的教育。有趣的实验将包括空气，水和土壤分析，法医研究以及统计设计的优化。新的环境科学计划还为痕量金属分析的可用性至关重要。 外展活动将是该项目不可或缺的一部分。一系列多年的仪器研讨会将向一大批中学教师和学生介绍先进的现代仪器。研讨会将强调基本原则，深入的动手工具经验以及现实生活中的应用。此外，新的光谱仪将广泛用于高中学生研究。
