Temperature dependences of the distribution coefficients of hydrophobic solutes onto porous styrene divinylbenzene resin for the eluent with a low methanol content.

The distribution coefficients of four hydrophobic solutes onto a porous styrene divinylbenzene resin were measured using methanol-water mixtures with a low methanol content as the eluent at various temperatures. The temperature dependence of the distribution coefficients indicated that the elution times of the solutes were controllable by elevating the temperature even for the eluent with a low methanol content.
