Abstract
The present invention relates to a method, a measuring cell and a system for measuring very small heat changes in a sample. The system comprises a measuring cell for containing the sample during the measurement process, at least one electromagnetic radiation unit for radiating one or several samples with modulated monochromatic or polychromatic radiation inside said measuring cell . Said measuring cell comprises at least one acoustic transducer for generating a first output signal V(t) and at least one heat measuring device for generating a second output signal T(t). Both signals are connectable to a combining unit that generates an information signal by means of a reference signal f(t). Said information signal is connectable to a signal processing unit for determining at least one relevant reaction parameter as a function of the measured heat change.
