  • Scan adiabatic resistive calorimeter (SARC) with ohm heating in the sample
    Patent number: 8613545
    Abstract: The present invention describes a scan adiabatic resistive calorimeter (SARC) 1 with ohm heating of the sample 20, which measures the heating enthalpy and is formed of an inner cylinder 11 and a couple of pistons 15 and 16, thus forming said elements a cylindrical chamber hermetically closed 10, which avoids that during its operation can be material losses by leaks. Pistons 15 and 16 have, in one of their ends an electrode 31 and 36 respectively and they pass the electrical heating flow through the sample 20. In reference to this electric flow, the applied power is calculated and therefore, the supplied heat to the sample 20, which is equal to the specific enthalpy. To assure that the whole of the electric flow is conducted through the sample 20, the inner cylinder 11 is electrically isolated.
