Size exclusion chromatography (SEC) is the most practical method of characterizing the molecular weight (MW) and molecular weight distribution of synthetic polymers, biopolymers and natural polymers. It is also known as gel permeation chromatography (GPC) or gel filtration chromatography (GFC). The pore size, pore size distribution and pore volume of media of size exclusion column have great effects on the separation of polymers.

Hydrocell GPC 1500 column is produced from a single batch of wide pore distribution of polystyrene-divinylbenzene (PS-DVB) beads with the average particle size of about 10 µm. It will provide more consistent results of analysis and separation of synthetic polymers.
