  • Chromatographic column for rapid characterizations of polymers
    Patent number: 6416663
    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. The described methods, systems, and devices have primary applications in combinatorial polymer research and in industrial process control.

  • Parallel high-performance liquid chromatography with serial injection
    Patent number: 6296771
    Abstract: High-performance liquid chromatography (HPLC) methods and systems are disclosed that combine sequential, serial injection of a plurality of samples into mobile-phases supplied in parallel to two or more chromatographic columns, such that staggered, parallel separation of the plurality of samples is effected. Because injection of samples is relatively fast as compared to separation, substantial efficiencies are gained with respect to overall sample throughput.
