<p>Method for determining the specific heat capacity (c p ) of a medium with a calorimeter, which comprises a reactor (1), a stirrer (3), an inner thermostat (A), an outer thermostat (B) and a control unit, characterized in that a modulated energy profile is applied to the medium which is arranged inside the reactor (1) under near isothermal conditions; the resulting energy changes of the medium, the reactor (1), the inner thermostat (A) and/or the outer thermostat (B) are monitored as a function of the time; an inner heat balance and an outer heat balance are determined independently at predefined time intervals; the overall heat transfer coefficient (UA) and the specific heat capacity of the medium (C p ) are calculated simultaneously and independently as a function of time.</p> |
