Chemistry (12)Electrochemiluminescence (ECL), combining elements of electrochemistry and photochemistry, involves the production of light near an electrode surface by species that can undergo highly energetic electron transfer reactions. ECL is a powerful technique that can be used to study a variety of analytes (e.g., organic, inorganic, biochemical). It is unfortunate that it is usually thought of as a tool only of the research and clinical laboratory since using analytical techniques that have "real-world" applications (e.g., in the clinical analysis of biomolecules) can greatly enhance teaching at the undergraduate level. We are adapting experiments from the research and educational literature and are developing new experiments, all of which use ECL techniques that can be carried out using an ECL analyzer. These experiments are being implemented in laboratory courses across our general chemistry and analytical curriculum, including courses for non-science majors and courses enrolling pre-service teachers. For example, in Fundamentals of Chemistry and in Chemistry for the Citizen students study claims about the purity of bottled water by determining the amount of copper in commercial water samples. Therefore, this state of the art instrument makes it possible for students to actually carry out environmental and water testing analyses. In Quantitative Analysis ECL allows the incorporation of quality assurance/quality control and regulatory issues into the undergraduate curriculum. Our goal is to have students gain experience with ECL techniques, and develop an appreciation for the applicability of these techniques to a wide range of problems. These improvements also reflect modern analytical science and emphasize the development of sound analytical technique while exposing students to the types of problems dealt with by professionals in the real world. A secondary goal is to modernize the undergraduate curriculum and to produce graduates who are competent in the use of modern instrumentation. The ECL analyzer also is being used in undergraduate research projects. Evaluation of the project will occur in a number of ways, including pre-and post-exposure assessment in the affected courses, and compilation of data from exit interviews with our senior majors. Procedures for the new experiments will be made available on the internet, and tested experiments will also be published in appropriate journals.

化学(12)电化学发光(ECL)结合了电化学和光化学的元素，涉及可发生高能电子转移反应的物种在电极表面附近产生光的过程。ECL是一种强大的技术，可用于研究各种分析物(如有机、无机、生化)。不幸的是，它通常只被认为是研究和临床实验室的工具，因为使用具有“现实世界”应用的分析技术(例如，在生物分子的临床分析中)可以极大地提高本科水平的教学。我们正在改编研究和教育文献中的实验，并开发新的实验，所有这些实验都使用可以使用ECL分析仪进行的ECL技术。这些实验正在我们的普通化学和分析课程的实验室课程中实施，包括非理科专业的课程和招收入职前教师的课程。例如，在《化学基础》和《面向公民的化学》中，学生通过测定商业水样中的铜含量来研究瓶装水的纯度。因此，这种最先进的仪器使学生能够实际进行环境和水测试分析。在量化分析方面，ECL允许将质量保证/质量控制和监管问题纳入本科课程。我们的目标是让学生获得ECL技术的经验，并培养对这些技术在广泛问题中的适用性的欣赏。这些改进还反映了现代分析科学，强调发展健全的分析技术，同时让学生接触到现实世界中专业人员处理的问题类型。第二个目标是使本科课程现代化，并培养出能够使用现代仪器的毕业生。ECL分析仪也被用于本科生的研究项目。对该项目的评估将通过多种方式进行，包括在受影响的课程中进行暴露前和暴露后的评估，以及汇编与我们专业四年级学生的毕业面试数据。新实验的程序将在互联网上公布，经过测试的实验也将在适当的期刊上发表。
