Incorporating Gas Chromatography/Mass Spectrometry into a Project-Based Laboratory

该项目使该机构能够获得瓦里安3400 气相色谱仪，使大二水平的有机- 分析实验室采用强大的GC/MS 光谱仪进入实验室。 使用该仪器 瓦里安3300/芬尼根MAT系统。 学生 在秋季学期， 以表征从混合物中分离的未知组分。 学生广泛使用仪器与GC/MS在 第二个术语是在多个步骤中表征和分析产品 合成。 对仪器的需求被一个 化学和物理的入学人数增加 由于时间限制和谨慎， 让每个学生寻找合适的色谱 设备上的条件。 该机构为该项目提供了相当于 国家科学基金会的资金

This project has allowed the institution to acquire a Varian 3400 Gas Chromatograph to enable the sophomore level Organic- Analytical Laboratory to incorporate a strong GC/mass spectroscopy segment into the laboratory. The instrument is used with the department's Varian 3300/Finnigan MAT system. Students are first instructed on these instruments in the fall term in order to characterize unknown components separated from mixtures. Students make extensive use of the instrument with the GC/MS in the second term to characterize and analyze products in multistep syntheses. The need for the instrumentation was heightened by an increase in enrollment in chemistry, and the physical impracticality caused by both time constraints and caution in having every student search for suitable chromatographic conditions on equipment which was in hand. The institution has contributed to the project in an amount equal to the NSF funds.
