Abstract

A calorimeter (1) with a decomposition chamber (3) with a combustion chamber (2), in which a receiving device (4) for a sample, an ignition device (5), and at least one supply line (6) for oxygen are provided. The decomposition chamber (3) is surrounded by a liquid or water jacket (7) into which at least one temperature sensor (8) extends. The liquid or water jacket (7) is surrounded by an outer container (9), which is a pressure container and which absorbs pressure generated during the combustion of a sample in the decomposition chamber (3) at the walls (10) thereof as a result of a tight sliding fit (15) by way of the water or the incompressible liquid. The decomposition chamber (3) therefore has an accordingly thin wall so that the heat generated during combustion of a sample can reach the temperature sensor or sensors (8) quickly.
