Abstract: An analysis of the time-varying calorimetric systems used in the study of molecular mixtures obtained by continuous injection is presented from the point of view of signal processing. A complete recipe to perform the identification and deconvolution of the thermal output is given, which enables rather complex systems to be dealt with, i.e. calorimeters whose time-invariant transfer function presents not only real poles but non-negligible zeros as well. The recipe has been deduced following a theoretical study of a model which represents rather accurately the actual behaviour of a heat-conduction calorimeter used in the study of continuous liquid mixtures.
