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

该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-质谱仪器来改善有机化学，环境化学和分析化学的教学。具体来说，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信息，而不仅仅是从课本和计算机练习中学习质谱。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的大一课程的入门体验。仪器的自动化功能加快了数据收集的速度，使学生有可能获得利用质谱数据进行鉴定的光谱数据库的计算机检索以及利用光谱解释工具协助确定未知化合物结构的宝贵经验。此外，该仪器正在一个由学生控制的环境分析实验室中使用，该实验室正在支持一个新的环境科学项目和设施的课程。

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.
