Acquisition of a Gas Chromatograph - Mass Spectrometer System for Undergraduate Teaching and Research

本项目提供一套气相色谱仪质谱计系统，该系统由一台惠普6890型气相色谱仪和一台惠普5973型质量选择检测器组成。该仪器系统通过让学生获得质谱和气相色谱质谱的第一手经验，用于弥补我们仪器持有中最显着的缺陷。学生还将学习计算机接口仪器和光谱数据库搜索的原理。气相色谱仪-质谱仪系统贯穿于整个化学课程，包括化学专业、其他理科专业和非理科专业的课程。平均每年有330名学生参加这些课程。仪器系统在每门课程中的使用都是这样一种方式，从入门课程到高级课程，在实验室技能和对气相色谱法和质谱法的概念理解方面都有一个进展。气相色谱-质谱系统也促进了许多学生和教师的研究项目，包括正在进行的胶束光化学反应的研究，桥接或笼状金属配合物合成的新图，稳定粘土胶体上金属配合物催化反应的产物，用于研究分子内催化原理的分子，用于新半导体材料的氨基六allane前体，不寻常的吡啶类化合物溴化的烯丙醇和非烯丙醇。

This project provides a gas chromatograph mass spectrometer system consisting of a Hewlett Packard model 6890 gas chromatograph and a Hewlett Packard model 5973 mass selective detector. This instrument system is used to remedy the most significant deficiency in our instrument holdings by allowing students to gain first-hand experience with mass spectrometry and with gas chromatography mass spectrometry. Students also learn the principles of computer-interfaced instrumentation and of spectral database searching. The gas chromatograph mass spectrometer system is used throughout the chemistry curriculum, including courses for chemistry majors, other science majors, and non-science-majors. On average, 330 students per year enroll in these courses. The instrument system is used in each course in such a way that there is a progression, both in laboratory skills and in conceptual understanding of gas chromatography and mass spectrometry, from the introductory courses through the advanced courses. The gas chromatograph mass spectrometer system also enhances many student-faculty research projects, including ongoing studies of photochemical reactions in micelles, new legends for the synthesis of bridged or caged metal complexes, products of metal complex-catalyzed reactions on stabilized clay colloids, molecules designed to study the principles of intramolecular catalysis, aminogallane precursors for new semiconductor materials, and unusual pyridine rinds and brominated allylic and nonallylic alcohols.
