Thermal Analysis and Calorimetric Methods

During investigation of a new material it is unlikely that any single thermal analysis technique will provide all the information required to understand its behavior. Complementary information is usually needed, which may be from another simultaneous thermal technique such as thermogravimetric-differential scanning calorimetric-mass spectrometry (TG-DSC-MS), gas chromatography (TG-GC, or DSG-GG), or spectroscopic methods such as IR spectroscopy or X-ray photoelectron spectroscopy (XPS). 

All these techniques, whether used by themselves or coupled to other techniques, are fully described in extended reviews [1-3]. 

Static or flow adsorption microcalorimetry, less extensively used, is a very powerful method for describing surface reactions and merits a more detailed overview. 

In heterogeneous gas-solid systems, a catalytic reaction proceeds according to the following stages adsorption of the reactant on the surface of the catalyst, reaction on the surface, desorption of the products from the surface. AH these steps
