Instrumentation
All intstruments used enables measurement under an oxidation atmosphere (air 5N) or inert atmosphere (nitrogen 5N, argon 5N, helium 5,5N). Only the aforementioned gases are available in the laboratory.
Thermogravimmetric and differential thermal analysis combined with mass spectrometry (TG-DTA-MS)
For evolved gas analysis (EGA), a combination of a TG-DTA thermal analyser (Setaram Setsys Evolution, France; operating range of 25–1600 °C) with an OmniStarTM quadrupoule-type mass spectrometer (Pffeifer Vacuum, Germany) is used.
Differential scanning calorimeter (DSC)
A DSC 131 (Setaram, France) is used with the following operating ranges: (i) from -150 °C to 400 °C; (ii) from ambient temperature up to 600 °C (in oxidation atm.), eventually 700 °C ( in inert atm.). Isotherms or scanning rates slower than 5 °C/min in an oxidation atm. are limited to a temperature of 500 °C. It is recommended that DSC requirements are discussed with laboratory staff in advance.
Differential scanning calorimeter DSC 3+ (Mettler Toledo, Switzerland) can be used within the temperature range (-80)°C up to 700°C in oxidation or inert atmosphere. Enables analysis in temperature-modulated DSC (TM-DSC).
Simultaneous thermogravimmetric and differential scanning calorimetry (TG-DSC)
Uniquely in the field of thermal analysis, TG-DSC is carried out using a Setaram Sensys Evo thermal analyser (France; operating range from -120 °C to 800 °C) equipped with a symmetrical balance and a Calvet 3D sensor.
Thermogravimetric analysis combined with fourier transform infrared spectroscopy (TGA-FTIR)
For evolved gas analysis (EGA), a combination of a Pyris 1 thermogravimetric analyser (Perkin Elmer, USA; operating range of 40–800 °C) and a Perkin Elmer Frontier infrared spectrometer is used.
