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

本项目提供了一个由Hewlett Packard 6890型气相色谱仪和Hewlett Packard 5973型质量选择检测器组成的气相色谱质谱仪系统。 该仪器系统是用来弥补我们的仪器持有量最显着的不足，让学生获得与质谱和气相色谱质谱的第一手经验。 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-质谱联用系统在化学课程中广泛应用，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名学生报名参加这些课程。 仪器系统在每门课程中的使用方式是，从入门课程到高级课程，在实验室技能和对气相色谱和质谱的概念理解方面都有进步。 气相色谱质谱仪系统还增强了许多学生和教师的研究项目，包括正在进行的胶束中光化学反应的研究，桥接或笼状金属络合物合成的新传说，稳定粘土胶体上金属络合物催化反应的产物，旨在研究分子内催化原理的分子，新半导体材料的氨基镓烷前体，以及不常见的吡啶皮和溴化烯丙醇和壬烯丙醇。

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.
