Heat flow calorimeter by Regenass

Just before publication of the described compact TKR calorimeter the so-called heat-flow calorimeter by Regenass was released. Measurement of the thermal reaction power under thermal conditions is carried out by that calorimeter, similarly by remodels [40, 41, 46] and knock-offs as follows.

The heat released from a sample during a process flows into the calorimeter and would cause a temperature change of the latter as a measuring effect this thermal effect is continuously suppressed by compensating the respective heat flow. The methods of compensation include the use of latent heat caused by a phase transition, thermoelectric effects, heats of chemical reactions, a change in the pressure of an ideal gas (Ter Minassian and Million, 1983), and heat exchange with a liquid (Regenass, 1977). Because the last three methods are confined to special cases, only the compensation by a physical heat of transition and by electric effects are briefly discussed here.
