Gas Chromatography - Mass Spectrometry in the Undergraduate Curriculum

本项目将气相色谱-质谱法引入本科课程。该仪器用于学生的动手实验，使他们能够更好地看到理论概念和所获得的数据之间的关系。气相色谱质谱服务实验室的概念也已实施。要做到这一点，一个自动进样器是必要的，并通过该项目获得。培训学生接受其他课程学生提供的样品进行气相色谱-质谱分析，运行样品并根据需要返回实验室结果并提供解释。无论学生是继续研究生教育还是立即进入工作岗位，这些经历都是实用而有价值的。在色谱柱技术、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。该机构获得了惠普GC-MS带自动进样器和NIST质谱库。该仪器的一个突出和重要的应用是在环境分析中，因此获得了一个吹扫和捕集器。使用GC- ms的实验在入门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和挥发性无机物（如螯合物和羰基）的合成中完成。该仪器也用于学生在他们的研究项目，在他们的大四和演示/视频演示，非科学学生的必修课程。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资金相当于国家科学基金会的资金。

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.
