A Computer Based Gas Chromatograph-Mass Spectrometer for a Modern Chemistry Curriculum

随着化学对仪器的日益重视，密西西比学院在化学课程中引入了气相色谱-质谱联用仪（GC-MS）。该仪器的使用和应用影响着有机化学和分析化学以及仪器分析专业的所有学生，并加强了我们的本科研究计划。GC-MS使用台式系统，计算机访问和控制，并允许识别复杂的混合物，数据存储，并在大型数据库中进行比较搜索。学生使用GC-MS的经验使他们能够更好地为研究生和专业学校或行业做好准备。具体的课程改进包括增加对天然材料、化学反应产物、环境污染物和药物的定性有机分析的仪器强调。质谱的理论是由实验支持的，在高级课程中，分离科学和质谱结合计算机辅助的重要性是有经验的。该机构正以等额的资金配合国家科学基金的拨款。

Consistent with the increasing instrumental emphasis in chemistry, Mississippi College is introducing a gas chromatograph-mass spectrometer (GC-MS) into its chemistry curriculum. Use and application of this instrument affects all students in organic and analytical chemistry, and instrumental analysis, and strengthen our undergraduate research program. The GC-MS uses a benchtop system, computer accessed and controlled, and allows identification of complex mixtures, data storage, and comparisons searching within a large library of data. Student experience with GC-MS compliments present powerful analytical methods thus better preparing them for graduate and professional schools or industry. Specific course improvements include increasing the instrumental emphasis in qualitative organic analysis of natural materials, products of chemical reactions, environmental contaminants and drugs. Theory of mass spectrometry is supported by experiments and in advanced classes the importance of integrating separation science and mass spectroscopy with computer assistance is experienced. The institution is matching the NSF grant with an equal amount of funds.
