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.
