Thermal analysis - DSC, DTA, TGA (SETSYS Evolution TGA-DTA/DSC SETARAM).
We use DTA, DSC and TG primarily for study of phase transformations, for determination of the fusion heat and the specific heat capacity.
Definition of thermal analysis - TA: Group of physical chemical methods which deal with studying materials and processes under conditions of programmed changing's of the surrounding temperature.
DTA = Differential Thermal Analysis -signal is temperature (time) dependence of the temperature difference between sample and reference
DSC = Differential Scanning Calorimetry – measures temperature (time) dependence of the heat energy that is consumed by the sample, the measurement of thermal capacity is possible.
TGA = Thermogravimetric Analysis – measures the sample mass versus T with high accuracy
