Abstract
Apparatus and methods are disclosed for performing power compensation in a differential scanning calorimeter. The device operates by first subjecting only a reference material, in a single furnace, to a predetermined, variable, temperature program supplied by a program control. The values of the heating power supplied to the reference material are stored in a memory as a function of the temperature measured at the single furnace by a temperature sensor. The sample is then exposed, in the same furnace, to heating powers which are consecutively applied to the furnace, under program control, in accordance with the values stored in memory. The real temperatures of the sample are then measured by the temperature sensor. A supplementary compensating heating power is supplied to the sample, which power varies in accordance with the difference between the stored, programmed temperature and the real temperature in the sense of eliminating this temperature difference. This supplementary compensating heating power is then outputted to and registered, respectively, at an output device such as a recorded or computer.
