A thermal method of analysis is a technique in which measure a physical property of a material as we subject it to a change in temperature. In this chapter we consider three examples of thermal methods: thermogravimetry, differential thermal analysis, and differential scanning calorimetry.

31.1: Thermogravimetry
One method for determining the products of a thermal decomposition is to monitor the sample’s mass as a function of temperature, a process called a thermogravimetric analysis (TGA) or thermogravimetry.
31.2: Differential Thermal Analysis and Differential Scanning Calorimetry
Differential thermal analysis (DTA) and differential scanning calorimetry (DSC) are similar methods in which the response of a sample and a reference to a change in temperature. In DTA the temperature applied to the sample is increased linearly and the difference between the temperature of the reference material and the temperature of the sample is recorded as function of the sample's temperature
