Gas Chromatography/Mass Spectrometry in the Undergraduate Chemistry Curriculum

通过该项目，该机构能够购买具有直接插入探针和正化学电离能力的气相色谱仪/质谱仪。学生在必修的入门级有机和无机课程、高级仪器分析和分子结构测定课程、独立学习和荣誉研究中使用该仪器。无机化学和微型有机化学实验室的学生在使用直接插入探针功能通过电子冲击电离对合成产物进行表征时，会被介绍质谱的基本原理。在经历了基本的电子冲击质谱分析之后，参加高级仪器分析和分子结构与测定课程的学生将电子冲击与正化学电离结合起来进行分子量和结构测定。学生使用气相色谱仪分析混合物。质谱仪的所有功能都用于学生在有机化学、环境研究和分析化学领域的独立学习和荣誉研究。该机构为该项目提供的资金几乎是美国国家科学基金会资金的两倍。

Through this project, the institution was able to purchase a gas chromatograph/mass spectrometer with direct insertion probe and positive chemical ionization capabilities. The students use this instrument in required introductory level organic and inorganic courses, in upper level instrumental analysis and molecular structure determination courses, and in independent study and honors research. Students in the inorganic chemistry and Microscale Organic chemistry laboratories are introduced to basic principles of mass spectrometry when they use the direct insertion probe capabilities for the characterization of synthetic products by electron impact ionization. After the experience with basic electron impact mass spectrometry, students enrolled in upper level instrumental analysis and molecular structure and determination courses use electron impact in conjunction with positive chemical ionization to make molecular weight and structure determinations. Students use the gas chromatograph for the analysis of mixtures. All capabilities of the mass spectrometer are used by students participating in independent study and honors research in areas of organic chemistry, environmental studies, and analytical chemistry. The institution contributed to this project in an amount nearly twice the NSF funds.
