Application Summary AI generated
This standard specifies the universal calibration method for determining the average molecular mass and molecular mass distribution of polymers using size-exclusion chromatography. It is applied in the plastics and rubber industries for quality control and material characterization, particularly when analyzing polymers with different chemical structures or branching. The method enables accurate molecular weight measurement by correlating hydrodynamic volume across various polymer types, making it essential for research, production, and product development.
