DYNAMIC BEHAVIOR OF POWER COMPENSATED DIFFERENTIAL SCANNING CALORIMETERS .2. THE SIGNAL FLOW

The dynamic behaviour of the measured signal of a power compensated DS C is studied in terms of linear response taking into account the measu ring system, the sample, the reference, the control circuits, the heat transport coefficients and the heat losses. As a result it is shown t hat the apparatus (or Green's) function of the DSC (including sample a nd heat transfer) is different from that necessary to desmear the samp le heat flow. The quality of the extracted Green's function is discuss ed for different measuring conditions.
