The measurement of the change in mass of a sample with temperature is performed on a thermobalance and is known as thermogravimetry.
Differential scanning calorimetry is a technique for measuring the heat flux of a sample and a reference material as a function of temperature. The signal obtained is the energy absorbed or emitted by the sample.
The simultaneous TGA-DSC equipment measures both parameters at the same time, making it a valuable tool for characterising the physical and chemical properties of materials under controlled atmosphere conditions.
TGA/DSC equipment with 34-position autosampler. Oven up to 1100 °C. High resolution balance. Possibility of coupling with FT-IR spectrometry equipment for the analysis of decomposition products.
Some of the phenomena and thermal processes that can be determined by TGA/DSC are:
- Adsorption and desorption of gases: fusions.
- Crystallisations.
- Process kinetics: polymorphisms.
- Sublimation, evaporation and vaporisation: phase diagrams.
- Thermal stability: Glass transitions.
- Oxidation reactions: kinetics.
- Identification by decomposition products: heat capacity.
- Transition and reaction enthalpies
- Pseudopolymorphisms
- Determination of Curie temperatures.
