Determining gases or vapors dissolved and/or absorbed in solids or on outer or inner surfaces of the solid comprises carrying out calorific and dielectric measurements in an impedance calorimeter. Determining gases or vapors dissolved and/or absorbed in solids or on outer or inner surfaces of the solid comprises carrying out calorific and dielectric measurements in an impedance calorimeter. The calorimeter consists of a thermostat (1) containing a thermostat fluid (13), a storage chamber (2) for the gas or vapor (15), a sorption chamber (3), a pressure line (4) connecting the chambers and containing a regulating valve (5), an electrical capacitor (6) filled with the sorbing liquid (7), pipe lines (10) for filling and emptying the chambers, a system of thermocouples (12) arranged in the walls of the chambers, and a measuring sensor (14) for determining the temperature and pressure in the chambers.
