Based on the physical meaning of each term in the linear parameter log I (a constant correlating the affinity of solut e t o stationary phase) of stoichiometric displacement model for retention o f solute, the thermodynamic characteristics of log I of solute in revers ed-phase liquid chromatography were investigated theoretically. This poi nt was tested by experimental data with two linear relationships:(1) plot of log I vs 1/T with apolar, polar small solut es and proteins;(2) plot of log I vs log Po/w (partition co effi cient of solute between n-octanol and water) with apolar and polar smal l solutes.
