Improvement of Teaching Laboratories and Student Research Using an Atomic Absorption Spectrometer

该项目有四个主要目标：（1）通过提供用于痕量金属分析的原子吸收（AA）光谱仪，提高学生在一般，分析和环境化学方面的实验室经验-该仪器使该部门能够为学生提供使用强大的分析工具解决具有极大内在兴趣的问题的实践经验;（2）为高年级生物学和环境科学学生提供更广泛的机会进行实地和实验室研究;（3）扩大高级研究项目的范围，使更多的定量研究成为可能，并鼓励发展合作项目;和（4）提供一个重要的工具资源，丰富学生参加环境实习计划的经验，与波特兰水区，缅因州环境资源部和附近社区合作。

This project has four major objectives: (1) to improve the laboratory experience of the students in general, analytical, and environmental chemistry by providing an atomic absorption (AA) spectrometer for trace metal analysis--this instrument enables the department to give students practical experience working with a powerful analytical tool on problems that have great intrinsic interest; (2) to provide broader opportunities for upper-level biology and environmental science students conducting field and laboratory research; (3) to enhance the scope of senior research projects, making possible more quantitative studies and encouraging the development of collaborative projects; and (4) to provide an important instrumental resource that enriches the experience of students participating in an environmental internship program, working in cooperation with the Portland Water District, the Maine Department of Environmental Resources, and nearby communities.
