Gel Permeation Chromatography (GPC), also known as Size Exclusion Chromatography (SEC), is a powerful analytical technique used to determine the molecular weight distribution of polymers and macromolecules. The instrument separates molecules based on their hydrodynamic volume, with smaller molecules penetrating the pores of the stationary phase and eluting later, while larger molecules elute first. GPC is essential in industries such as plastics, pharmaceuticals, biotechnology, and petrochemicals for quality control, research, and development. The global GPC market has seen steady growth, driven by increasing demand for polymer characterization and stringent regulatory standards.
