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.

现代仪器是强大的分析工具，在最初的有机化学实验室中强调它们的使用，在那里学生学习气体和高效液相色谱仪(GC、HPLC)，以及红外、核磁共振、紫外线和质谱仪。这些仪器，特别是IR和GC，不仅被广泛用于反应和蒸馏产物的简单分析，而且还被用于分离复杂的混合物，以检验机械假说(碳阳离子重排)。本科生的研究在该机构受到越来越多的重视。在一所小型大学中，所有仪器不仅服务于初级实验室和高级实验室，也服务于研究生院，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需求。通过这一项目，该研究所升级了其有机化学仪器。他们获得了易于教授的傅里叶变换红外光谱和毛细管气相色谱。新的仪器提供了明显更好的数据，允许进行几个新的实验，并使教员能够教授新技术。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。
