Abstract
The character of the temperature dependences of the retention indices RI(Т) of polar sorbates on nonpolar stationary phases was found to depend on the dosed amounts of sorbates, but not on column overloading. A physicochemical model was suggested to explain the observed anomalies in RI(Т).
