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.

Description of services:

  • monitor weight and mass change during gas uptake or release when the material is being heated
  • determine the enthalpy of a process taking place in a sample
  • determine if a process occuring in a sample is exothermic or endothermic
  • calculation of water content in chemical precursors
  • thermal decomposition study of inorganic compounds and polymers
  • identification of phase transitions and calculation of their enthalpies
  • degree of crystallinity
  • 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.
