Abstract Three capillary columns of Superox 20M, two of them immobilized in different ways, were prepared. All columns showed a transition zone from adsorption of the solutes at low temperatures to absorption at higher temperatures. The minimum allowed operating temperature of the column was found to change from 64°C to 50°C when the polymer was immobilized. Partial molar enthalpies of mixing showed that alkanes are poor solvents of the stationary phase, while aromatics are good solvents, with… CONTINUE READING
