Gas Chromatography-Mass Spectrometry Instrumentation in the Undergraduate Curriculum

该项目的目的是为学生提供气相色谱/四极杆质谱仪器，在一系列本科分析和有机化学课程中进行基于探究的实验室实验。四极杆质谱联用气相色谱仪（GC/MS）为有机化合物的鉴定和定量提供了一种简单而有力的技术。一些化学教育文献中描述的实验正被改编为适合当地使用，从大一/大二的入门分析课程开始。目标课程还包括最近为化学专业学生开设的以环境科学为重点的环境化学课程，以及为打算在中学教学的学生和非化学专业学生开设的应用仪器分析课程。在仪器分析课程中，将介绍更先进的质谱理论和通过实验室实验的应用。除了分析课程外，参加有机化学实验室和本科研究项目的学生也可以获得实际的GC/MS经验，在这些项目中GC/MS可以成为一个有价值的工具。在需要分析复杂样品的工业实验室中，使用GC/MS仪器是非常常见的。学生有机会获得GC/MS技术的重要实践经验是至关重要的。

The objective of this project is to provide students with gas chromatography/ quadrupole mass spectrometry instrumentation to carry out inquiry-based laboratory experiments in a series of undergraduate analytical and organic chemistry courses. Quadrupole mass spectrometry techniques with gas chromatograph (GC/MS) offer a simple but powerful technique for the identification and quantitation of organic compounds. A number of experiments described in chemical education literature are being adapted for local use starting with an introductory analytical course at the freshman/ sophomore level. Target courses also include a recently developed environmental chemistry for chemistry majors with an environmental science emphasis, and an applied instrumental analysis course taken by those intending to teach at the secondary school level as well as by non-chemistry majors. More advanced mass spectrometry theory and applications via laboratory experiments are being presented in an instrumental analysis course. In addition to analytical courses, hands-on GC/MS experiences are being obtained by students enrolled in organic chemistry laboratories and undergraduate research projects, where GC/MS can be a valuable tool. The use of GC/MS instruments is very common in industrial laboratories where analysis is required of complex samples. It is essential that students have the opportunity for significant hands-on experiences with GC/MS techniques.
