GPC/SEC is a size separations technique employed to separate complex mixtures of macromolecules according to their hydrodynamic size. If the chemistry of the sample(s) is known, then appropriate setup conditions such as solvent, solvent additives, experimental temperature, and column setup can be suggested.
