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

该项目使该机构获得了一台瓦里安3400气相色谱仪，使二年级的有机分析实验室能够将强大的GC/质谱部分纳入实验室。该仪器与该部门的Varian 3300/Finnigan MAT系统一起使用。在秋季学期，学生们首先学习这些仪器，以表征从混合物中分离出来的未知成分。在第二学期，学生将广泛使用该仪器和GC/MS来表征和分析多步合成中的产物。由于化学专业注册人数的增加，对仪器的需求增加了，而且由于时间的限制和每个学生在手头的设备上寻找合适的色谱条件的谨慎，导致了物理上的不实用性。该机构已为该项目提供了相当于国家科学基金会基金的金额。

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.
