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

When it comes to determination of the linear thermal expansion in solids, liquids, powders and pastes as well as ceramic fibers, the DIL 402 C vacuum-tight pushrod dilatometer leaves no measurement problem unsolved. The perfect design of the Invar measurement system with its high-resolution displacement transducer and comprehensive thermostatic control offers the highest degree of accuracy, reproducibility and long-term stability for application temperatures up to 2000°C.
The horizontal design of the dilatometer with motorized pushrod and easy to move furnace make it simple to place samples on the special sample supports in the recess of the tube-type sample carrier, even with less than ideal sample geometries. A thermocouple in direct proximity to the sample yields reproducible temperature measurement. This also allows use of the c-DTA® Software for calculation of endothermic and exothermic effects in the sample as well as determination of all the characteristic expansion values.
