KOPTRI professionally measures the molecular weight of crystalline polymers in polyolefin group that are insoluble in room temperatures by utilizing High Temperature-GPC (Gel Permeation Chromatography).

Eluent used to measure the molecular weight of polyolefin for high-temperature GPC is TCB(1,2,4-trichlorobenzene). Mechanical properties of Polyethylene or polypropylene will significantly affected on its molecular weight, molecular weight distribution, and branching, which requires quality control with GPC. Please give us a separate inquiry for ultra-high molecular weight polyethylene with a molecular weight of over a million. If semiconducting polymers such as polythiophene (aromatic conjugated polymer) does not dissolve in chloroform, we use TCB-GPC to measure the molecular weight.
