WebOct 15, 2002 · Alternatively, data can be presented as a derivative thermogravimetric (DTG) curve, which is a plot of the rate of change of mass with respect to time or temperature against time or temperature. The DTG mass losses should also be plotted downward and the gains upward. Thermogravimetric analysis (TGA) is conducted on an instrument referred to as a thermogravimetric analyzer. A thermogravimetric analyzer continuously measures mass while the temperature of a sample is changed over time. Mass, temperature, and time are considered base measurements in thermogravimetric analysis while many additional measures may be derived from these three base measurements.
