Incorporating Gas-Chromatography/Mass Spectrometry (GC/MS) into a Teaching and Faculty-Mentored Student Research Curriculum

气相色谱/质谱（GC/MS）是现代化学家使用的一项基本仪器技术。化学系正在调整许多来源的实验，将气相色谱/质谱结合到他们的教学实验室和教师指导的学生研究计划中。GC/MS作为化学分离、化合物鉴定和定量工作的工具被引入有机化学两课。在定量分析中，学生探索实际的GC/MS仪器问题，并进行更深入的定量实验。完成定量分析后，学生将进入几个高年级课程，每个课程都使用GC/MS，例如在有机光谱学中使用GC/MS， FTIR和NMR分析复杂的有机混合物。在环境化学实验室中，学生通过一系列的实验来探索GC/MS在环境分析中的各个方面。最后一轮是由学生设计，对当地土壤/水样中的污染物进行原始调查。学生还利用GC/MS调查当地土壤/水样中的农药/除草剂水平，作为环境科学实习中综合环境管理计划的一部分。在指定的研究课程中，学生使用GC/MS研究有机污染，分析新树突和复合离子的反应混合物以优化纳米颗粒的合成条件，通过水解去除核碱基来研究DNA损伤，并扩展现有的GC/MS分析方法，分析古代骨骼/陶器中发现的脂质，用于分析古代岩画（岩画）。

Chemistry (12)Gas-chromatography/mass spectrometry (GC/MS) is a fundamental instrumental technique used by modern chemists. The Chemistry faculty are adapting experiments from many sources to incorporate GC/MS into their teaching laboratories and faculty-mentored student research program. GC/MS is introduced in the Organic Chemistry two-course sequence as a tool for chemical separations, compound identification, and quantitative work. In Quantitative Analysis, students explore practical GC/MS instrumental concerns and perform more intensive quantification experiments. After completing Quantitative Analysis, students move into several upper division courses, each using GC/MS, such as analysis of a complex organic mixture using GC/MS, FTIR, and NMR in Organic Spectroscopy. In Environmental Chemistry laboratory, students rotate through a series of experiments where they explore aspects of GC/MS in environmental analysis. The final rotation involves student-designed, original investigations of pollutants in local soil/water samples. Students also utilize GC/MS to investigate pesticide/herbicide levels in local soil/water samples as part of a comprehensive environmental management plan in the Environmental Science Practicum. In designated research courses, students use GC/MS to study organic pollution, analyze reaction mixtures of new dendrimers and complex ions to optimize conditions for the synthesis of nanoparticles, investigate DNA damage by removal of nucleobases via hydrolysis, and expand existing methodologies of GC/MS analysis of lipids found in ancient bone/pottery for the analysis of ancient rock paintings (petroglyphs).
