In the characterization of polymers, size-exclusion chromatography (SEC) has become a standard technique for determining molar mass averages andmolar mass distributions (MMD) of polymers. The principle of SEC is easily understood: owing to limited accessability of the pore volume within the particles of the column packing, polymer molecules are separated according to their hydrodynamic volumes,...

Separation of macromolecules on the basis of their molecular weight by size exclusion chromatography has long been considered to be caused by the geometry-dependent partition of macromolecules between a continuous phase and the porous interior of a gel or cross-linked bead. The volume of a pore accessible to a solute is limited by its relative dimensions, so larger molecules will have access to...
