The amount of internal solvent in Merckogel OR-2000 has been determined for ten different solvents using polystyrene (mol. wt., 10,000) as the excluded solute. In this method, dry gel is equilibrated with an organic solution containing a known concentration of a solute which is excluded by the gel. The internal solvent volume of the swollen gel is calculated from the concentration change due to mixing. There are distinct relations between the amount of internal solvent, a solubility parameter and the molar volume of the solvent.
