Gas Chromatography/Mass Spectrometry (GCD) for Improved Undergraduate Instruction

自然科学系正在通过为所有大一工程，科学和化学学生提供各级气相色谱/质谱（GCD）领域的实验工作来加强本科化学实验室课程。每年有200名大一新生在化学实验室进行相关实验。 购买GCD设备加强了目前提供的每一个实验室课程。重要的是，通过化学课程的学生进步有机会使用这种现代仪器技术;因此，现代仪器的化学专业的培训正在保险。 GCD在同位素分析和氟里昂等空气污染物的环境研究中的相关性正在大学化学中引入，并通过有机化学和高级合成继续进行，其中反应产物结构测定和鉴定通过使用这种仪器得到加强。在物理化学中，学生使用GCD计算热力学性质和Arrhenius反应速率参数。在仪器分析中，提供了定量测量空气，土壤和水中痕量污染物的额外实验。 实验室的指导是通过使用计算机和软件已经在质谱解释支持。在新的环境化学课程的学生也受益于环境研究的仪器的使用。 在大学化学实验室中使用GCD设备，是入门课程的关键组成部分，鼓励学生强烈的兴趣，并导致改善招聘，保留和培训积极和合格的化学专业。

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.
