Abstract
A variable temperature PhotoAcoustic (PA) cell built on a conventional Differential Scanning Calorimeter (DSC) is described. It can operate between 300 and 800 K and allows to perform PA and DSC measurements si multaneously. The frequency and temperature characteristics of the cel l are examined using standard samples. The utilities of this combined PA-DSC cell for studying different types of phase transitions, such as solid - liquid, structural and glass transitions, are demonstrated.
