Gel filtration

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.
