Integration of a Gas Chromatograph Mass Spectrometer into the Undergraduate Curriculum

化学（12）随着学生在本科有机化学、定量分析、仪器分析方法、高级合成实验室和本科研究中使用GC/MS，该奖项允许以增量方式将GC/MS引入课程。通过仔细选择仪器组件，增量方法允许在大注册的低级别实验室和低注册的高级别实验室中使用GC/MS。实验是根据研究和教育文献改编的，并采用基于探究的教学法实施到我们的课程中。增量方法从解释同位素质量和丰度数据所需的概念开始，然后继续进行复杂物种的破碎模式，精确分析复杂混合物所需的技术，以及通过使用库软件进行鉴定。最后，对GC/MS工作原理的良好介绍为我们在高级仪器分析方法和高级合成课程以及本科研究项目中的复杂应用提供了基础。这种方法是通过各种各样的经验来发展学生对这种技术力量的理解和欣赏。学生的创造性思维能力和解决问题的能力不断提高。GC/MS的安装是我们整个实验室现代化/技术集成工作的延续。

Chemistry (12)This award is permitting the introduction of GC/MS in an incremental fashion into the curriculum as students are using this instrument in undergraduate organic chemistry, quantitative analysis, instrumental methods of analysis, advanced synthetic laboratories, and undergraduate research. Through a careful selection of instrument components, the incremental approach is allowing the use of the GC/MS in both large enrollment lower-division and lower enrollment upper-division laboratories. Experiments are being adapted from the research and the educational literature and implemented into our curriculum using an inquiry-based pedagogy. The incremental approach begins with the concepts needed to interpret isotopic mass and abundance data, and then continues with fragmentation patterns of complex species, techniques required for the accurate analysis of complex mixtures, and identifications through the use of library software. Finally, a sound introduction to the operating principles of GC/MS is providing the foundation for sophisticated uses in our upper-division instrumental methods of analysis and advanced synthesis courses and in undergraduate research projects. This approach is developing the student's comprehension of and appreciation for the power of this technique through a variety of experiences. The creative thinking skills and problem solving abilities of students are being improved. The installation of the GC/MS is a continuation of our overall Laboratory Modernization/Technology Integration Effort.
