Adding Gas Chromatography-Mass Spectrometry to Chemistry and Environmental Chemistry Laboratories

这个项目的主要目标是通过在这些课程的实验室部分增加气相色谱-质谱仪来改进有机化学、环境化学和分析化学的教学。具体地说，新系统使学生能够获得他们在实验室中使用的化合物和混合物的质谱学信息，而不仅仅是从文本和计算机练习中了解质谱学。除了在有机化学、分析化学和环境化学课程中使用外，它还被用于专业和非专业一年级课程的入门体验。仪器中包含的自动化加快了数据收集速度，使学生有可能获得宝贵的经验，使用大量光谱数据进行鉴定，并使用光谱解释工具来帮助确定未知化合物的结构，以计算机搜索光谱数据库。此外，该仪器正在一个由学生参与的环境分析实验室中使用，该实验室正在为一个新的环境科学计划和设施的课程提供支持。

The main goal of this project is to improve instruction in Organic Chemistry, Environmental Chemistry, and Analytical Chemistry by adding gas chromatography-mass spectrometry instrumentation to the laboratory component of these courses. Specifically, the new system enables students to acquire mass spectral information on compounds and mixtures they are using in the laboratory rather than merely to learn about mass spectrometry from text and computer exercises. In addition to its uses in Organic Chemistry, Analytical Chemistry, and Environmental Chemistry courses, it also is being used for introductory experiences in freshman level courses for majors as well as non-majors. The automation included in the instrument speeds data collection and makes it possible for students to gain valuable experience in computer searching of spectral data bases using mass spectral data for identification as well as using the spectral interpretation tools to assist in determining the structure of an unknown compound. In addition, the instrumentation is being used in a student-manned environmental analysis laboratory that is supporting courses in a new environmental science program and facility.
