Separation, Identification, Quantitation: Incorporating the Power of the Gas Chromatograph-Mass Spectrometer into the Undergraduate Curriculum

通过这个项目，气相色谱仪与质谱仪（GC/MS）的接口被包含在四年的化学课程中。该仪器用于高级班级，充分利用了GC/MS组合的强大功能。此外，GC/MS还用于中低级别的类。例如，化学入门课中氯仿的质谱分析说明了氯仿的各种同位素，并允许计算它们的相对强度。通过将GC/MS连接到网络（其中已经包括傅里叶变换核磁共振仪器），该仪器甚至可以并入最大的实验室部分。计算机实验室包含六个终端（每个工作站最多允许三个学生），毗邻仪器室；本项目包含仪器软件的六个附加版本的许可证。由于在课程早期就提供了先进的仪器，化学专业的学生的经验得到了加强。此外，选修较低级别的化学课程的地球科学和生物学学生也会接触到先进的仪器。*

Through this project, a gas chromatograph interfaced to a mass spectrometer (GC/MS) is included in all 4 years of the chemistry curriculum. The instrument is used in upper-level classes, making full use of the power of the GC/MS combination. In addition, the GC/MS is used in middle- and lower-level classes. For example, analysis of the mass spectrum of chloroform in introductory chemistry illustrates the various isotopes of chloroform and allows calculation of their relative intensities. The instrument can be incorporated even into the largest laboratory sections by connecting the GC/MS to a network (which already includes a Fourier-transform nuclear magnetic resonance instrument). The computer laboratory contains six terminals (allowing three students maximum per station) and is adjacent to the instrument room; licenses for six additional versions of instrument software are included in this project. With advanced instrumentation provided early in the curriculum, chemistry majors have their experiences reinforced. Additionally, geoscience and biology students who take lower-level chemistry are exposed to advanced instrumentation. *
