Size Exclusion Chromatography and Thermal Analysis as Teaching Tools in Polymer, Biophysical, and Physical Chemistry

为了在高年级物理化学实验课程中增加新的实验，该大学正在购买热分析和尺寸排除色谱仪器。该设备具有广泛的教学用途，既可以作为新开发的高分子科学导论课程中一系列表征实验的基石，也可以作为生物物理和物理化学实验室的一部分。几个实验使用差示扫描量热法和尺寸排除色谱法作为主要工具，被用于将设备整合到高年级本科生实验室。这些实验包括对聚乙烯、两种高性能复合材料（聚醚酮和化学性质相似的聚酯）、琼脂糖凝胶和二元萘-二苯胺体系中的热行为的检查，以及对聚苯乙烯、聚甲基丙烯酸甲酯和纤维素聚合物中分子量概念的分析。增加这些实验可以提高大学的本科实验课程的现代化和跨学科的重点。

In order to add new experiments across the upper-division Physical Chemistry laboratory curriculum, the university is purchasing thermal analysis and size-exclusion chromatography instrumentation. This equipment has a wide range of instructional uses, both as a cornerstone to a series of characterization experiments in the newly developed Introduction to Polymer Science course and as a part of the Biophysical and Physical Chemistry laboratories. Several experiments that use differential scanning calorimetry and size-exclusion chromatography as primary tools are being used to integrate the equipment into the upper-division undergraduate laboratories. These experiments include an examination of the thermal behavior in polyethylene, two high-performance composite materials (polyetheretherketone and a polyester of similar chemical nature), agarose gel, and the binary napthalene-diphenylamine systems, as well as an analysis of molecular weight concepts in the polystyrene, polymethylmethacrylate, and cellulose polymers. Adding these experiments can improve the university's undergraduate laboratory curriculum in terms of modernization and interdisciplinary focus.
