Abstract: Process and device for photothermal and/or calorimetric analysis of gaseous, liquid and solid test material (24), by detuning an ultrasonic resonator (1). Said resonator comprises a mutually opposed ultrasonic emitter (2) and ultrasonic receiver (3). The signal whose amplitude or phase relation are analysed by the analyser (5) provides information concerning thermal variations in the ultrasonic resonator designed as a gas cell or calorimeter, based on the temperature-dependent velocity of sound. The device discloseed is suitable for detecting gases and for calorimetric analysis of test materials in particular light-conducting elements (50) such as optical fibres.
