Abstract: | Scanning transitiometry combines three state variables (P,V,T) with a heat effect measured in strictly defined thermodynamic
conditions. By slowly scanning one of the state variables when the other one is kept constant, the transitiometer permits
to determine simultaneously two thermodynamic derivatives, always one is thermal and the other one mechanical. This study
presents a number of applications of scanning transitiometry in various fields (dense liquids, supercritical systems, polymers,
food systems) and presents results, often impossible to obtain with other known techniques. |
