Polymers are macromolecules composed of many repeating subunits. What makes these materials unique is that many of their properties depend strongly on size (molecular weight). This means that molecular weight determination is part of the basic, routine analysis performed on every sample, no matter how routine; the industry standard in measuring molecular weights is size exclusion chromatography (SEC) / gel permeation chromatography (GPC). This application requests a high-temperature SEC/GPC system. The instrument will be used to analyze polymers from two research chairs with well-funded research programs and a strong track record of innovative research. Kelly is a Tier 2 Canada Research Chair in Photovoltaics and Acharya is the Saskatchewan Ministry of Agriculture Chair in Bioprocess Engineering. The polymers made in the Kelly group are used as advanced materials in electronic applications, including solar cells and transistors. His work on organic solar cells aims to bring this highly manufacturable, low-cost photovoltaic technology out of the laboratory and into commercial production. In contrast, Acharya's team is focused on adding value to agriculture biomass; here, the polymers are the result of a biorefining process. The biorefining processes developed by Acharya's team will produce versatile plastics and adhesives from sustainable and biodegradable feedstocks. In both cases, the measurement of polymer molecular weights is a crucial part of the work. These advances will help grow Canada's technology and sustainability sectors, creating new jobs in green energy, polymer synthesis, biorefining, and sustainable materials production. It is expected that 50+ students and post-doctoral fellows will be trained on the SEC/GPC system over the next five years, providing skilled workers to these growing industries.

聚合物是由许多重复的亚基组成的大分子。这些材料的独特之处在于，它们的许多性质强烈依赖于大小(分子量)。这意味着，无论多常规，测定分子量都是对每个样品进行的基本常规分析的一部分；测量分子量的行业标准是尺寸排除层析(SEC)/凝胶渗透层析(GPC)。此应用程序需要高温SEC/GPC系统。该仪器将用于分析来自两个研究椅子的聚合物，这些椅子拥有充足的研究计划和良好的创新研究记录。凯利是加拿大二级光伏研究教席，阿查里亚是萨斯喀彻温省农业部生物过程工程教席。凯利集团生产的聚合物被用作包括太阳能电池和晶体管在内的电子应用中的先进材料。他在有机太阳能电池方面的工作旨在将这种高度可制造、低成本的光伏技术从实验室带到商业生产中。相比之下，阿查里亚的团队专注于增加农业生物质的价值；在这里，聚合物是生物精炼过程的结果。Acharya团队开发的生物精炼工艺将从可持续和可生物降解的原料中生产多功能塑料和粘合剂。在这两种情况下，聚合物分子量的测量都是这项工作的关键部分。这些进展将有助于发展加拿大的技术和可持续发展部门，在绿色能源、聚合物合成、生物精炼和可持续材料生产方面创造新的就业机会。预计未来五年将有50多名学生和博士后接受SEC/GPC系统的培训，为这些不断增长的行业提供熟练工人。
