'I'hc volus~~ outsiclc of the resin pnrticlcs in an ion-cschnngc column is ca.llctl tllc interstitial, void, or free vohimc and is often denoted by I/. In tllc plate tlleory of ion-cSchIlgc clution chromato~Taphyl and of the closdy rchtcd Salting-Out2 ant1 solubilization" types of chromatography, the interstitial volume is an important paramctcr. 'I'hc distribution ratio, C, (the quantity of any p'articiilar solute in tllc resin phase of any plate dividccl by the quantity in tlic interstitial solution of tlic same plate) is readily calculated from an c,spcrimcntal clution qaph by the equation c=(u+/V
