This project introduced gas chromatography-mass spectrometry into the undergraduate curriculum. The instrument is used by students in hands-on experiments so they will better see the relationship between theoretical concepts and the data obtained. The concept of GC-MS Service Laboratory has also been implemented. To do this, an autosampler was necessary and was acquired through this project. Students are trained to accept samples for GC-MS analysis from students in other courses, to run them and to return the laboratory results with explanations as needed. The experiences are practical and valuable whether students go on to graduate education or enter the working force immediately. Recent advances in column technology, instrument design, electronics and software have made this application a fesible project. The institution acquired the Hewlett-Packard GC-MS with autosampler and the NIST library of mass spectra. One prominent and important application of the instrument is in environmental analysis so a purge and trap collector was acquired. Experiments using GC-MS are done in the introductory and advanced organic laboratory , analytical and instrumental laboratories, physical chemical experiments that emphasize the use of GC to measure physical properties, and synthesis of volatile inorganics such as chelates and carbonyls. The instrument is also used by students in their research projects in their senior year and for demonstrations/video presentations in required courses for non- science students. The availability of the instrument had an immediate impact on the undergraduate curriculum. The institution contributed to this project in an amount equal to the NSF funds.

本项目将气相色谱-质谱学引入本科课程。学生在动手实验中使用该仪器，这样他们就可以更好地看到理论概念和获得的数据之间的关系。气质联用服务实验室的概念也得到了落实。为了做到这一点，需要一个自动取样器，并通过这个项目获得了它。学生接受了接受其他课程学生的GC-MS分析样品的培训，运行这些样品，并根据需要返回带有解释的实验室结果。无论是继续研究生教育还是立即进入劳动力大军，这些经验都是实用和有价值的。最近在柱技术、仪器设计、电子学和软件方面的进步使这一应用成为一个可行的项目。该机构获得了带有自动进样器的惠普GC-MS和NIST质谱库。该仪器的一个突出而重要的应用是在环境分析中，因此获得了吹扫和捕集收集器。使用GC-MS的实验在初级和高级有机实验室、分析和仪器实验室、强调使用GC测量物理性质的物理化学实验以及挥发性无机物的合成(如螯合物和羰基)中进行。该仪器也被学生在他们大四的研究项目中使用，并在非理科学生的必修课中用于演示/视频演示。该仪器的使用对本科生的课程设置产生了直接影响。该机构为该项目提供的资金相当于国家科学基金会的资金。
