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.

该项目将气相色谱-质谱法引入本科课程。 学生使用该仪器进行动手实验，以便他们更好地了解理论概念与所获得的数据之间的关系。 GC-MS 服务实验室的概念也已得到实施。 为此，需要一个自动进样器，并且是通过该项目获得的。 学生接受培训，接受来自其他课程学生的 GC-MS 分析样品，运行这些样品并返回实验室结果并根据需要进行解释。 无论学生继续研究生教育还是立即进入职场，这些经验都是实用且有价值的。 色谱柱技术、仪器设计、电子和软件方面的最新进展使该应用成为一个可行的项目。 该机构购买了带有自动进样器的惠普 GC-MS 和 NIST 质谱库。 该仪器的一个突出且重要的应用是环境分析，因此购买了吹扫捕集收集器。 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螯合物和羰基化合物等挥发性无机物的合成中进行。 该仪器还供学生在高年级的研究项目中以及非理科学生必修课程的演示/视频演示中使用。 该仪器的可用性对本科课程产生了直接影响。 该机构为该项目提供的捐款金额相当于 NSF 资金。
