TG-DTA is a thermal analysis technique that measures the weight change of a sample (thermogravimetry, TG), and endothermic and exothermic reactions based on the difference in temperature between the sample and a reference (differential thermal analysis, DTA) during a programmed temperature change. It can measure the weight changes associated with dehydration or decomposition, and the temperatures of endo/exothermic reactions such as melting and transition. TG 8121 with sample observation attachment, a new entry in the Thermo plus EVO2 series, allows visual observation of the sample by a CCD camera mounted directly above the specimen while performing conventional TG-DTA measurements.
