(57) [Summary]nDisclosed is rapid characterization and screening of polymer samples to determine average molecular weight, molecular weight distribution and other properties. Rapid flow characterization systems and methods, including liquid chromatography and flow injection analysis systems and methods, are preferably used. High throughput, automated sampling systems and methods, high temperature characterization systems and methods, and rapid indirect calibration compositions and methods are also disclosed. The described methods, systems and devices have major applications in combinatorial polymer research and industrial process control. |
