Derivative thermogravimetry
WebApr 10, 2024 · Another kind of representation of the results is the derivative thermogravimetry (DTG), which is the first derivative of the TGA curve. Hence, it describes the mass change rate. DTG is also used to detect … The first derivative of the TGA curve (the DTG curve) may be plotted to determine inflection points useful for in-depth interpretations as well as differential thermal analysis . A TGA can be used for materials characterization through analysis of characteristic decomposition patterns. See more Thermogravimetric analysis or thermal gravimetric analysis (TGA) is a method of thermal analysis in which the mass of a sample is measured over time as the temperature changes. This measurement provides … See more Thermogravimetric analysis is often combined with other processes or used in conjunction with other analytical methods.
