Thermogravimetry and calorimetry
The thermogravimetry and calorimetry is a part of the NAFUMA laboratory.
The Netzsch STA449F1 Jupiter (top) and the STA449C Jupiter (bottom) Simultaneous Thermal Analysers (STA) for TGA, TGA-DTA and TGA-DSC types of measurement. The latter is connected to a QMS403 Aëolos mass spectrometer.

- analysis of glass transitions
- experiments performed to determine vapor pressure.
About the thermogravimetry and calorimetrey
The simple principle of TGA is to heat up a sample placed on a sensitive weight to monitor the mass change of a sample undergoing reactions involving gas uptake or release. A sample can be studied under a wide range of atmospheres, or even vacuum. The STA combines the TG technique with one of two other complementary thermal analysis techniques that are also sensitive to transitions or processes not associated with a mass change. The first of these complementary techniques is Differential Scanning Calorimetry (DSC), which is a quantitative technique for determining the enthalpy of a process taking place in the sample. The other, Differential Thermal Analysis (DTA), is a qualitative method for determining if a process occurring in the sample is exothermic or endothermic.
