Use of Gas Chromatography/Electron Ionization Detection in an Innovative Lab-Oriented Curriculum

本项目的重点是在新开发的化学课程中纳入惠普GCD，一种带有电子电离检测器的毛细管气相色谱仪。 发展新课程的两个指导原则是：（1）课程应以发现为基础，学生应积极参与科学探究;（2）应消除传统上分隔化学分支学科的界限。 新的课程包括一个学期，发现为基础的入门课程，其次是中级和高级课程，继续说明化学的跨学科性质。 Hewlett-Packard GCD是一种两用仪器，可作为毛细管GC或GC/MS操作。 因此，该仪器将填补仪器的两个重要空白，并将广泛用于新化学专业所需的八门核心课程中的四门，以及高级选修课和独立研究项目。 来自其他学科的大量专业也参加了这四门课程中的两门，将这种仪器纳入新课程的影响扩展到化学系之外。

This project focuses on the inclusion of a Hewlett-Packard GCD, a capillary gas chromatograph with an electron ionization detector, in a newly developed chemistry curriculum. The two guiding principles in developing this new curriculum are (1) courses should be discovery-based with students being actively engaged in scientific inquiry and (2) the boundaries which have traditionally separated the subdisciplines of chemistry should be removed. The new curriculum includes a 1-semester, discovery- based introductory course and is followed by intermediate and upper-level courses that continue to illustrate the interdisciplinary nature of chemistry. The Hewlett-Packard GCD is a dual use instrument in that it may operate as a capillary GC or as a GC/MS. As such, this instrument will fill two important gaps in instrumentation and will be extensively used in four of the eight core courses required for the new chemistry major, as well as in advanced electives and in independent research projects. A significant number of majors from other disciplines also enroll in two of these four courses, extending the impact of the inclusion of this instrument in the new curriculum beyond the doors of the chemistry department.
