Modernization of the Instruments in Organic Chemistry Laboratory

现代仪器是强大的分析工具，在有机化学实验室的初级课程中，学生将学习气相色谱和高效液相色谱（GC、HPLC），以及红外、核磁共振、紫外和质谱。这些仪器，尤其是红外和气相色谱，不仅广泛用于反应和蒸馏产物的简单分析，而且用于复杂混合物的分离，以测试机制假设（碳正离子重排）。该机构越来越重视本科生的研究。在一所小型学院中，所有的仪器不仅服务于初级和高级实验室，而且也服务于研究学生，因此这些仪器必须在苛刻的条件下产生高质量的数据，并且必须足够灵活以满足意想不到的新要求。通过这个项目，该机构升级了其有机化学仪器。他们获得了易于教学的傅里叶变换红外和毛细管柱气相色谱。新的仪器提供了明显更好的数据，允许进行一些新的实验，并使教师能够教授新技术。该机构为该项目提供的资金相当于国家科学基金会的资金。

Modern instruments are powerful tools of analysis and their use is emphasized in the beginning organic chemistry laboratory, where the students learn of gas and high performance liquid chromatographs (GC, HPLC), and infrared, nuclear magnetic resonance, ultraviolet, and mass spectrometers. These instruments, especially the IR and GC, are used extensively not only for simple analysis of products from reactions and distillations but for the separation of complex mixtures to test mechanistic hypotheses (carbocation rearrangements). Undergraduate research is receiving increased emphasis at the institution. In a small college all instruments serve not only the beginning and upper class labs but the research students as well, so these instruments must produce quality data under demanding conditions and must be flexible enough to meet unanticipated new demands. Through this project, the institution upgraded its organic chemistry instrumentation. They acquired an easy-to-teach Fourier-transform IR and a capillary column GC. The new instruments provided significantly better data, allowed several new experiments to be performed, and enabled the faculty to teach new technologies. The institution contributed to this project in an amount equal to the NSF funds.
