| Abstract: | Summary: Selected examples of using 3D-GPC-TREF to solve polyolefin characterization problems are described in this paper. The term 3D-GPC-TREF stands for a home-build hybrid system of gel permeation chromatograph (GPC) coupled with the capability of the temperature rising elution fractionation (TREF) that includes three online detectors, i.e. the infrared (IR), the differential-pressure viscometer (DP), and the light scattering (LS) detectors. |
