Abstract. The development of the Discontinuous lsoperibolic Thermal Analysis (AITA) aims at setting up a new phase diagram investigation technique efficient in the case of organic component systems. A heterogeneous system (with at least one liquid phase) is kept in isoperibolic conditions and submitted to discontinuous composition shifts by successive additions of a thermostated solvent (or solution). It results in perturbations of the equilibrium state and then physical phenomena which bring the system back to the equilibrium. The phenomena resulting fkom the addition of liquid (dissolution, dilution.. .) imply enthalpy changes which cause temperature variations of the system. An adapted exploitation of the temperature versus time signals leads to the determination of the topology of the corresponding phase diagram.
