New differential scanning calorimeter. New thermochemical applications

The described calorimeter is of fluxmetric, differential type. Thanks to the surrounding arrangement of the heat-flux-sensor, the sensitivity is independent of the sample characteristics: size, container type, kind of gas etc. Application to high-pressure experiments, is outlined. The general arrangement gives direct access to the sensitive zone from the outside: direct introduction of the sample; setting of electrical, mechanical, or pneumatic connections; application to the study of “open” chemical systems (gas-solid reactions). Examples of application are given.
