Thermal Analysis and Physico-chemical properties (SATePC)

All the versions of this article: English , français

The objectives of this platform is to give access to researchers to various techniques for physico-chemical and thermodyanmic properties It gives access also to very strong and specialized human competences in thermal analysis and thermodynamics (calorimetry, thermogravimetry, phase equilibriums) and in physico-chemical analysis (potentiometry, transport properties, densitometry).

a consorium agreement has been signed between ICCF and CALNESIS : CALNESIS will be in charge of external prestations, in their domain of knowledge, and if the partner is agreeing with this.

- Properties of interest

THERMAL ANALYSIS AND THERMODYNAMICS
• Calorimetry (phase transitions (enthalpy and temperature), heat capacity, mixing enthalpies)
• Thermogravimetry (mass losses, vaporization, degradation, possibly coupled with mass spectrometer and humidity controler)

PHYSICO-CHEMICAL PROPERTIES
• Potentiometry (pKa, Karl Fisher %, ppm H2O)
• Volumetric properties (density; (T, P), volumes)
• Transport properties (viscosity, electrical conductivity,infinite dilution diffusion coefficients)
