TGA - Thermogravimetric Analysis
Analytical technique description:
Thermogravimetric analysis (TGA) is an analytical technique dedicated to record mass variations of a studied sample in function of temperature or time, in a controlled atmosphere. The result of this kind of analysis is a thermic decomposition curve, which reports in abscissa temperature or time values and in ordinate mass variations as absolute or percentage values.
Applications:

Basics:
It is a method of thermal analysis in which changes in physical and chemical properties of a given material are recorded as a function of increasing temperature (with constant heating rate) or as a function of time (with constant temperature or constant mass loss).
