Purchase of a High Performance Recycling Size-Exclusion Chromatography System

化学研究仪器和设施（CRIF）计划的这一奖项将允许普渡大学化学系购买尺寸排阻色谱系统。 该仪器主要由初级教员亚历山大·魏（Alexander Wei）使用，他的研究重点是环状低聚苯胺和基于环苯胺的链状聚合物的预有机合成;以及构象修饰的碳水化合物的合成和固态结构。 尺寸排阻色谱法，也称为凝胶渗透色谱法，是用于有机和生物有机材料的分析分离和鉴定的成熟技术。 它也被广泛用于制备分离，其中特定的化合物可以从混合物中分离出来。 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.
