Multidisciplinary Use of High Performance Liquid Chromatography

厄尔勒姆学院通过对现有的高效液相色谱仪进行模块化升级和计算机化，将高效液相色谱仪（HPLC）引入生物和化学实验课程（并对心理学进行有限的介绍）。最近获得的一个等压泵加上一个梯度溶剂输送系统，两个检测器（可变波长紫外和折射率），一个记录器和一个基于微机的数据采集系统，以及几个通用和专用的色谱柱，允许与现有的HPLC一起组装三个完整的系统，以各种配置用于不同的应用。化学系、生物系和心理学系的学生将在跨学科模式下获得显著改善的实验室体验。七门课程以及所有三个系的学生研究都受到影响。

The introduction of high performance liquid chromatography (HPLC) into biology and chemistry laboratory courses (with a limited introduction into psychology) is being accomplished through the modular upgrading and computerization of an existing high performance liquid chromatograph at Earlham College. The recent acquisitions of an isocratic pump plus a gradient solvent delivery system, two detectors (variable wavelength UV and refractive index), a recorder and a microcomputer-based data acquisition system and several columns for general purpose and specialty use allows assembly, with the existing HPLC, of three complete systems in a variety of configurations for different applications. Students from the Departments of Chemistry, Biology and Psychology are being exposed to significantly improved laboratory experiences in an interdisciplinary mode. Seven courses are affected, as well as student research in all three departments.
