Abstract: Apparatus for GPC/TREF and TREF/GPC characterization of a polymer sample. The apparatus provides for the automated and integrated use of multiple TREF columns and a GPC system employing a multiple flow through detectors. In addition, a method for TREF/GPC characterization of a polymer sample by GPC analysis of TREF fractions at increasing TREF elution temperatures from multiple TREF columns operated in a coordinated and synchronized temperature cycle for increased sample throughput. Also, a method for GPC/TREF characterization of a polymer sample by GPC fractionation followed by TREF fractionation of the GPC fractionations.
