The Application of Gas Chromatography in Environmental Engineering Laboratory Curriculum

为了更好地培养学生，以满足对具有广泛专业知识的环境工程师的需求，正在修订实验室课程，将整个行业使用的分析设备包括在内。在这项提案中，需要资金购买惠普(HP)气相色谱仪(GC)、顶空采样器以及数据分析和处理系统。购买气相色谱仪将扩大学生接触的范围和材料，从而极大地提高本科环境工程专业的水平。这些设备将供参加环境工程本科实验室课程的学生、教师演示和参与学生发起的研究项目的本科生使用。拟议项目的主要目标是将气相色谱的使用纳入三个环境工程本科课程的实验室：环境工程原理(CE 170)、环境污染控制中的物理/化学过程(CE 175)和环境污染控制中的生物过程(CE 176)。该气相色谱仪将在CE170上使用，讲授气相色谱的基本原理和一般应用。实验室的发展侧重于在许多单元操作和单元工艺的设计和/或操作中应用气相色谱，这将为注册CE 175和CE 176的环境工程专业的学生提供“动手”的实验室体验。

In order to better prepare students to meet the demand for environmental engineers with a wide range of expertise, laboratory courses are being revised to include the use of analytical equipment used throughout the industry. In this proposal, funds are requested to purchase a Hewlett Packard (HP) gas chromatograph (GC), headspace sampler, and data analysis and handling system. Purchase of the gas chromatograph would greatly enhance the undergraduate environmental engineering program by expanding the scope and material to which the students are exposed. The equipment will be used by students enrolled in undergraduate environmental engineering laboratory courses, by faculty run demonstrations, and by undergraduate students involved in student originated research projects. The primary objective of the proposed project is to integrate the use of gas chromatography into the laboratories of three undergraduate courses in environmental engineering: Principles of Environmental Engineering (CE 170), Physical/Chemical Processes in Environmental Pollution Control (CE 175) and Biological Processes in Environmental Pollution Control (CE 176). The gas chromatograph will be used in CE 170 to teach the fundamental principles and general applications of gas chromatography. The development of laboratories that focus on the application of gas chromatography in the design and/or operation of a number of unit operations and unit processes will provide environmental engineering students enrolled in CE 175 and CE 176 a "hands-on" laboratory experience.
