DÉFINITION
- Thermogravimetry (TG) and Derivative Thermogravimetry (DTG): thermogravimetry allows the determination of the mass as a function of temperature or time; this thermal technique provides information concerning the thermal stability and composition of the sample and of any intermediate compound which may be formed. DTG curve represents the first derivative of the mass change curve; in this way a series of peaks are obtained instead of the stepwise curve in which the areas under the peaks are proportional to the total mass change of the sample.
