Acquisition of a High Temperature Gel Permeation Chromatography System

9977520马克主要研究仪器基金将用于购买聚合物分析仪器：高温凝胶色谱仪（GPC）和光散射检测器，配备氩离子激光器，以增加检测能力。 西北大学现有的GPC不具备聚合物尖端研究所需的高温能力或灵敏度。 这台新设备将安装在西北大学化学系的分析服务实验室。最大数量的用户将来自化学系，但化学工程系和材料科学与工程系也将有大量使用这种仪器的研究项目。 该设备将满足几个研究小组的需要，以表征聚合物样品的分子量，分子量分布和溶液中的流体动力学体积。 这项研究涵盖了广泛的主题，包括新的聚合催化剂，超分子聚集体的自组装，用于DNA测序的热响应聚合物，聚合物降解机制，半结晶聚合物的界面粘附和聚合物加工。 除了将受益于新仪器的重要研究外，还有一个强大的教育组成部分。研究生，博士后研究员和本科生使用该仪器进行研究将从使用最先进的仪器中获得实质性的好处。 此外，另一个好处将来自该仪器的正式教育部分，可用于实验室课程。 研究和教育应用相结合，将使更多的用户感受到这一设备的好处。主要研究仪器计划的资金将用于购买用于聚合物分析的凝胶渗透色谱仪。 该仪器将用于西北大学几个系的研究人员的各种项目。 该仪器将对学生的研究培训产生很大的影响，博士后到本科生，通过让他们在最先进的仪器上获得实践经验。

9977520 Marks Major Research Instrumentation funds will be used to acquire instrumentation for polymer analysis: a high temperature gel chromatograph (GPC) and a light scattering detector, equipped with an argon ion laser, for additional detection capability. The available GPCs at Northwestern University do not have the high temperature capability or the sensitivity needed for cutting edge research in polymers. This new equipment will be installed in the Analytical Services Laboratory of the Department of Chemistry at Northwestern University. The greatest number of users will come from the Department of Chemistry, but the Department of Chemical Engineering and the Department of Materials Science and Engineering will also have research projects making significant use of this instrumentation. The equipment will address the need of several research groups to characterize polymer samples in terms of their molecular weights, molecular weight distributions, and hydrodynamic volumes in solution. This research covers a broad range of topics including new catalysts for polymerization, self assembly of supramolecular aggregates, thermo-responsive polymers for DNA sequencing, polymer degradation mechanisms, interfacial adhesion of semicrystalline polymers, and polymer processing. In addition to the important research that will benefit from the new instrumentation, there is a strong educational component. The graduate students, postdoctoral fellows, and undergraduate students using the instrument for their research will receive substantial benefit from working with a state-of-the-art instrument. In addition, a further benefit will come from a formal educational component of the instrument being available for laboratory classes. The combination of research and education applications will allow the benefit of this equipment to be felt by an increased number of users. Major Research Instrumentation program funds will be used to acquire a gel permeation chromatograph for use in polymer analysis. This instrument will be use in a variety of projects of researchers in several departments at Northwestern University. The instrument will have a large impact on the research training of students, postdoctoral to undergraduate, by allowing them hands-on experience on a state-of-the-art instrument.
