Abstract
Rapid characterization and screening of polymer samples to determine average molecular weight, molecular weight distribution and other properties is disclosed. Rapid flow characterization systems and methods, including liquid chromatography and flow-injection analysis systems and methods are preferably employed. High throughput, automated sampling systems and methods, high-temperature characterization systems and methods, and rapid, indirect calibration compositions and methods are also disclosed, where the polymer sample, solvent, liquid chromatograph column and/or mobile phase eluant is heated to temperatures of at least 75 degrees Celsius during the sample injection or elution process. The described methods, systems, and devices have primary applications in combinatorial polymer research and in industrial process control.
