This project provides funds to purchase a Nicolet gas chromatography/Fourier-transform infrared (GC/FTIR) system, which is one of the primary instruments to be used in a new laboratory course entitled Analysis of Complex Mixtures in Complex Media. Used in conjunction with existing department analytical equipment and a microwave digestion unit provided by a local manufacturer, this instrument permits faculty to implement a program in which undergraduate chemistry majors are taught the laboratory techniques necessary to perform organic analysis of complex systems such as soils, water, biological samples, food, and other multicomponent mixtures. The purpose of this is to provide undergraduates, especially those whose terminal degrees are a bachelor's, the skills necessary to perform well in areas such as industrial or environmental chemical analysis. The GC/FTIR system plays an important role in these types of analysis, since the more popular mass spectrometer (MS) or GC/MS techniques often fail to provide the information necessary to distinguish between similar compounds (e.g., geometric and substitution isomers) of identical molecular weight.

该项目提供资金购买一套尼科莱气相色谱/傅里叶变换红外（GC/FTIR）系统，这是一门新的实验课程“复杂介质中复杂混合物的分析”中使用的主要仪器之一。与现有的部门分析设备和微波消解装置由当地制造商提供的结合使用，该仪器允许教师实施一项计划，其中本科化学专业的学生被教导必要的实验室技术来执行复杂系统的有机分析，如土壤，水，生物样品，食品和其他多组分混合物。这样做的目的是提供本科生，特别是那些终端度是学士学位，必要的技能，如工业或环境化学分析领域表现良好。GC/FTIR系统在这些类型的分析中起着重要的作用，因为更流行的质谱仪（MS）或GC/MS技术通常不能提供区分相似化合物所需的信息（例如，几何异构体和取代异构体）。
