Abstract
A method and an apparatus for the differential thermal analysis of materials includes heating a first sample to be investigated and a reference sample by radiation heat transfer from respective separated radiation sources, controlling both sources according to a predetermined temperature program for the samples, interposing an element that partly transmits radiation between each of the samples and their associated sources, sensing the temperature difference between the elements, controlling one of the radiation sources in response to the temperature difference to equalize the temperature of the elements and measuring the temperature difference between the samples during the temperature program.
