Evaluation of a Commercial Differential Viscometer as a GPC Detector and Its Application to Polymer Characterization

摘要

When used as a GPC detector, Viscotek's differential viscometer (DV) measures specific viscosities at each elution volume across the chromatogram. With the addition of a concentration detector, intrinsic viscosities may be calculated. As a result, true molecular weights can be calculated via the universal calibration method.
