Use of Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES) in Three Disciplines, From Introductory Courses to Student-Research Projects.

跨学科（99）本项目将元素分析的现代仪器纳入厄尔勒姆学院化学、生物学和地质学的基础科学课程。PI和团队选择了电感耦合等离子体-原子发射光谱仪（ICP-AES），因为它具有快速执行多元素分析的能力，这将允许更多的学生群体使用该仪器。三个预期结果指导了这个项目。第一，化学专业的学生和未成年人通过使用该仪器的标准课程中的实验室实验和学生与教师的研究项目，逐渐接触到ICP-AES的使用。第二，来自其他学科的学生，特别是生物学和地质学的学生，通过分析从他们自己学科的工作中获得的样本，正在获得化学信息在科学中所起的基本作用的经验。第三，厄勒姆大学的非科学专业学生正在使用该仪器分析环境问题研究中获得的数据。项目组希望对这些非理工科学生的理科倾向产生积极影响。支持使用该仪器的源材料正在从几个来源改编。这些包括美国化学学会的书，“化学背景下”（为非科学专业的入门课程），韦伯斯特等人的工作，DUE奖#9751439（在环境化学课程中调查纯净和污染土壤样品中微量金属的存在），以及唐尼等人的工作，DUE奖#9750867 （ICP-MS实验对ICP-AES实验的适应）。

Interdisciplinary (99) This project is incorporating modern instrumentation for elemental analysis throughout the basic science curriculum at Earlham College in chemistry, biology, and geology. The PI and team have chosen an inductively coupled plasma - atomic emission spectrometer (ICP-AES) for its rapid capacity to perform multi-elemental analysis, which will permit a larger student population to use the instrument. Three expected outcomes guide this project. One, chemistry majors and minors are gaining exposure to usage of the ICP-AES through laboratory experiments in their standard courses which use the instrument, and through student-faculty research projects. Two, students from other disciplines - in particular biology and geology - are gaining experience with the fundamental role that chemical information plays in science, by analyzing samples obtained from work in their own discipline. Third, non-science majors at Earlham are using the instrumentation to analyze data obtained in a study of environmental issues. The project team expects to positively influence the disposition of these non-science majors towards science. Source material to support the use of this instrumentation is being adapted from several sources. These include the American Chemical Society's book, "Chemistry in Context" (for the introductory course for non-science majors), the work of Webster et al., DUE award #9751439 (for investigating the presence of trace metals in pure and contaminated soil samples in an Environmental Chemistry course), and the work of Downey et al., DUE award #9750867 (adaptations of ICP-MS experiments to ICP-AES experiments).
