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.

本计画的目的是提供学生使用气相层析/四极杆质谱仪，在一系列分析与有机化学的本科课程中，进行探究式的实验室实验。 四极杆质谱技术与气相色谱仪（GC/MS）提供了一个简单而强大的技术，用于鉴定和定量的有机化合物。 化学教育文献中描述的一些实验正在适应当地使用，从大一/大二的介绍性分析课程开始。 目标课程还包括最近开发的环境化学与环境科学的重点化学专业，和那些打算在中学一级以及由非化学专业任教的应用仪器分析课程。 更先进的质谱理论和应用，通过实验室实验正在提出的仪器分析课程。 除了分析课程，动手GC/MS的经验正在获得就读于有机化学实验室和本科生研究项目，其中GC/MS可以是一个有价值的工具的学生。 GC/MS仪器的使用在需要分析复杂样品的工业实验室中非常常见。 重要的是，学生有机会获得GC/MS技术的重要实践经验。
