The Thermal and Textural analysis plateau offers two types of analyzes available at Lille or Lens. The plateau studies all requests from industrial or academic partners; depending on requirements, services or more or less long-term collaborations can be proposed.


The equipment park includes :

  • 3 multifunction analyzers for the study of:

- reduction and oxidation (TPR/TPO) of the samples

- adsorption and desorption of probe molecules by temperature programmed desorption (TPD) for acidity (NH3 and basicity (CO2) characterization

- metal dispersion (chemisorption H2, CO)


  • 7 analyzers for the study of the behavior of the sample as a function of temperature and under different atmospheres:

- 4 TGA-DSC for simultaneous recording of mass loss and heat flow to identify transformations and phenomena. Coupling with a mass spectrometer is also available.


TGA-MS coupling

Thermogravimetric analysis (TGA) is a technique that measures the mass variations of a sample that is heated, cooled or maintained at a constant temperature. It is mainly used to characterize the composition of materials. Its fields of application include plastics, elastomers, thermosets, minerals, ceramics as well as a wide range of analyzes in the chemical and pharmaceutical industries. Among others, the platform proposes a device having the advantage of offering an extended temperature range from ambient temperature up to 1600°C while measuring the heat flux by DSC (Lens).

Finally, TGA connected to a mass spectrometer allows to detect several thermal effects and mass spectroscopy analysis simultaneously.

- 2 DSC for enthalpies calculations, glass transitions and measurements of melting and crystallization temperatures

- 1 TGA for larger samples with the possibility to perform adsorption isotherms by gravimetry

  • 1 dilatometer for thermal expansion coefficient determination

  • 1 heating microscope analyses silhouettes of the test piece and determines geometric parameters and characteristics temperatures (sintering, softening, melting, …)

The equipment park includes :

  • 3 sorption analysers for full isotherms for porosity determinations (surface area, pore volume, pore size distribution)

  • 1 sorption analysers for Surface area measurement
