Purchase of a High Performance Recycling Size-Exclusion Chromatography System

这份来自化学研究仪器和设施（CRIF）项目的合同将允许普渡大学化学系购买一套尺寸排除色谱系统。该仪器将主要由Alexander Wei教授使用，他的研究主要集中在环低聚苯胺和环苯胺基共轭聚合物的预备有机合成；构象修饰碳水化合物的合成和固态结构。粒径排除色谱法，也称为凝胶渗透色谱法，是一种成熟的分析分离和鉴定有机和生物有机材料的技术。它也广泛用于制备性分离，其中可以从混合物中分离出特定的化合物。色谱法可以说是合成化学家和其他人可用的最强大的工具之一。这里支持的工作应该在聚合物化学领域产生重大影响。

This award from the Chemistry Research Instrumentation and Facilities (CRIF) Program will allow the Chemistry Department at Purdue University to purchase a size-exclusion chromatography system. This instrument is to be used primarily by Alexander Wei, a junior faculty member, whose research focuses on preparatory organic synthesis of cyclic oligoanilines and cycloaniline-based catenated polymers; and the synthesis and solid-state structure of conformationally modified carbohydrates. Size exclusion chromatography, also known as gel permeation chromatography, is a well-established technique for the analytical separation and identification of organic and bio-organic materials. It is also widely used for preparative separations, in which a particular chemical compound can be isolated from a mixture. Chromatography is arguably one of the most powerful tools available to the synthetic chemist, and others. The work supported here should have significant impact in the area of polymer chemistry.
