How 2D-LC work Gel Permeation Chromatography (GPC) is an analytical technique for the characterization of a wide variety of polymers or other macromolecules in a mixture. In GPC, a solution of dissolved sample is passed through a column with a controlled-porosity packing, typically a polymeric porous gel (typically referred to as a stationary phase) In contrast, the one uses organic solvent such as tetrahydrofuran (THF) or chloroform is called Gel Permeation Chromatograpny (GPC) or organic SEC. The first GPC method was developed by J.Moore in1964 US. The cross-linked polyethylene gel was used for the MW distribution analysis of synthesized polymers
