gel fil·tra·tion

separation of molecular sizes by passage of a mixture through columns of beads of cross-linked dextrans or similar relatively inert material of a well-defined pore size range; the larger the molecule, the less time it spends in the interior of the beads, thus emerging earlier from the column than smaller molecules.

gel filtration chromatography

A type of column chromatography in which chemicals are separated via pores according to their molecular size.
