Webanalyzing the sample are weight, rate of weight change—differential thermogravimetry, and temperature. A differential thermogravimetry curve—DTG—is generated as the first derivative of the weight with respect to temperature or time. The DTG curve can be used to provide both qualitative and quantitative information about the sample.
