In Thermogravimetric Analysis, both sample and reference are given an equal amount of energy. The device measures the difference in the temperature of the sample compared to the reference. If the sample is undergoing an endothermic process (absorbing heat), the temperature decreases, and the slope of the peak on the TGA power as a function of temperature curve is downwards sloping. If the sample is exothermic, then the peak is shifted upward. The area below the peak is the enthalpy change, which is proportional to the specific heat capacity of the material.<\/p>\n

Temperature ramp rate has a direct effect on the clarity of the peaks. When the heating is too rapid, not all the transitions can be detected properly, and accuracy is reduced. Modern TGA instruments will have a precision of 0.1 C on the peaks. This technique is applied for isothermal or non-isothermal crystallization studies.<\/p>\n","protected":false},"excerpt":{"rendered":"
