Triple detection Gel Permeation Chromatography (GPC) incorporating a Multi-Angle Laser Light Scattering (MALLS) detector is an important instrumentation for research on synthesis and characterization of polymers with tailor-designed chain architectures. The incorporated MALLS detector enables the matchless capability to accurately measure the absolute polymer molecular weight and distribution, polymer coil size and distribution, and many other important polymer structural properties. The funds are requested in this proposal to acquire a Wyatt miniDAWN MALLS detector for the establishment of a powerful triple-detection High-Temperature Gel Permeation Chromatography (HTGPC) system for the urgent need in Dr. Ye's research on chain architecture-controlled polyolefins. Dr. Ye currently has in his lab a Polymer Laboratory PL220 HTGPC system with a dual concentration and viscosity detector array. Owing to the lack of a MALLS detector, the capability and performance of the existing HTGPC system is significantly limited. Many important properties of polymers synthesized currently can not be fully and/or accurately characterized. The award of the requested detector will therefore tremendously boost the capability of the instrument and significantly help the successful progress of the research programs. The requested equipment is the first of its kind both at Laurentian University and in the region of Northern Ontario. Its acquisition is critical to the establishment of a cutting-edge polyolefin research field at Laurentian University and is important for the training and retention of high-qualified polymer researchers in the region of Northern Ontario and the rest of Canada.

结合多角度激光散射（mall）检测器的三重检测凝胶渗透色谱（GPC）是研究具有定制链结构聚合物的合成和表征的重要仪器。内置的MALLS检测器能够精确测量聚合物的绝对分子量和分布、聚合物线圈的尺寸和分布以及许多其他重要的聚合物结构特性。本申请申请资金用于购买Wyatt minidawwn MALLS检测器，用于建立强大的三重检测高温凝胶渗透色谱（HTGPC）系统，以满足叶博士对链结构控制聚烯烃的研究的迫切需要。叶博士目前在他的实验室拥有一个聚合物实验室PL220 HTGPC系统，该系统具有双浓度和粘度检测器阵列。由于缺乏一个mall探测器，现有HTGPC系统的能力和性能明显受到限制。目前合成的聚合物的许多重要性质还不能得到充分和/或准确的表征。因此，所要求的探测器的授予将极大地提高仪器的能力，并极大地帮助研究计划的成功进展。所要求的设备是劳伦森大学和安大略省北部地区的第一个此类设备。它的收购对于在劳伦森大学建立一个尖端的聚烯烃研究领域至关重要，对于在安大略省北部和加拿大其他地区培养和留住高素质的聚合物研究人员也很重要。
