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.

环境分析在罗阿诺克学院变得越来越重要，这是由于环境科学课程的引入和整个课程中基于多周应用的项目的广泛使用。这一新的重点产生了对金属痕量分析的需求，这将使用火焰/炉原子吸收光谱仪来满足。新的仪器特性包括改进的炉法检测限、背景校正能力和用于火焰分析的高温燃烧器。 新的实验和研究项目将在一个全面的四年仪器培训课程的背景下开发。仪器经验的多层次序列将用于教育学生的基本操作，先进的技术和基本原则。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。新的环境科学计划也创造了各种本科生的研究机会，其中微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。一个多年系列的仪器仪表讲习班将向大批中学教师和学生介绍先进的现代仪器仪表。研讨会将强调基本原理，深入的动手仪器经验，和真实的生活应用。此外，新的光谱仪将广泛用于高中学生的研究。
