The Department of Natural Sciences is enhancing the undergraduate chemistry laboratory curriculum by offering all freshman engineering, science, and chemistry students, at all levels, experimental work in the area of gas chromatography/mass spectrometry (GCD). Two hundred freshmen in the freshman chemistry laboratory, each year, are able to use this instrument in relevant experiments. Acquisition of GCD equipment strengthens each of the laboratory courses currently offered. It is important that students progressing through the chemistry curriculum have the opportunity to use this modern instrumental technique; therefore, training of chemistry majors on modern instrumentation is being insured. The relevance of GCD in isotope analysis and environmental studies of air pollutants such as freons is being introduced in University Chemistry and is continued through Organic Chemistry and Advanced Synthesis, where reaction product structure determination and identification is enhanced by the use of this instrument. In Physical Chemistry, students use GCD for the calculation of thermodynamic properties and Arrhenius reaction rate parameters. In Instrumental Analysis, additional experiments in quantitative measurement of trace contaminants in air, soil, and water are offered. Laboratory instruction is being supported by the use of computers and software already available in mass spectra interpretation. Students in the new environmental chemistry program also benefit from the use of the instrument for environmental studies. Use of GCD equipment in University Chemistry Lab, a key component of the introductory course, encourages strong student interest and leads to improved recruitment, retention, and training of motivated and qualified chemistry majors.

自然科学系正在加强本科生化学实验课程，为所有一年级的工程、科学和化学专业的学生提供在气相色谱/质谱学(GCD)领域的实验工作。每年有200名大一化学实验室的新生能够在相关实验中使用这种仪器。GCD设备的购置加强了目前提供的每一门实验室课程。重要的是，在化学课程中不断进步的学生有机会使用这种现代仪器技术；因此，对化学专业学生进行现代仪器培训是有保障的。GCD在氟里昂等空气污染物的同位素分析和环境研究中的相关性正在被引入大学化学，并在有机化学和高级合成中继续使用，使用该仪器加强了反应产物结构的确定和鉴定。在物理化学中，学生使用GCD计算热力学性质和阿累尼乌斯反应速率参数。在仪器分析中，提供了空气、土壤和水中痕量污染物的定量测量的附加实验。通过使用已有的计算机和已有的质谱学解释软件来支持实验室教学。新环境化学项目的学生也受益于环境研究仪器的使用。在大学化学实验室中使用GCD设备是入门课程的一个关键组成部分，它鼓励学生产生浓厚的兴趣，并有助于提高对有积极性和合格的化学专业学生的招生、留住和培训。
