SEC is a type of liquid chromatography, which enables the separation of molecules according to their size. The main characteristic of stationary phases are different sized pores. Smaller molecules enter these pores and therefore they move along the column slowly in comparison to larger molecules. Some molecules are too large to enter the pores and they are excluded and consequently have no retention.
