The Netzsch Simultaneous TGA/DTA is a thermal analysis instrument that measures both thermogravimetric (TGA) and differential thermal analysis (DTA) simultaneously with a single sample in a controlled environment (ie argon, nitrogen or compressed air) from room temperature to 1500ºC. TGA measures the change in weight of a sample with increasing temperature. The resulting curve provides information concerning the thermal stability and composition of the initial sample, as well as the thermal stability and composition of any intermediate compounds which may develop. DTA measures the difference in temperature between a sample and a thermally inert reference as the system temperature is varied. The resulting plot provides information on exothermic and/or endothermic reactions taking place, and determines transition temperatures.
