Simultaneous Thermal and Evolved Gas Analysis

Thermal analysis is a destructive analytical technique that investigates the behaviour of (nano) materials as a function of temperature. CATRIN-RCPTM uses a device for simultaneous thermal analysis (STA) combining thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC), coupled with quadrupole mass spectrometer for evolved gas analysis (EGA). This method offers information about the chemical composition of the sample, its thermal behaviour, transition points and its functionalization. STA can be performed in the temperature range from 45 °C to 1300 °C with controlled heating rate under synthetic air or inert atmospheres of nitrogen or argon.

 

Example: Thermograms in air combined with evolved gas analysis for Fe3S4 nanoparticles (a) free and (b) immobilized on a support. The thermal transformation of the nanoparticles produces SO/SO2 gases detected at distinct temperatures, evidencing the different environment of the studied material (from J. Mater. Chem. A, 2020, 8, 25716)
