Thermogravimetric analysis (TGA) is a powerful technique for the measurement of thermal stability of materials including polymers. In this method, changes in the weight of a specimen are measured while its temperature is increased. Moisture and volatile contents of a sample can be measured by TGA.

What is the function of TGA?

The TGA is responsible for regulating the supply, import, export, manufacturing and advertising of therapeutic goods.

How does thermal gravimetric analysis work?

In thermogravimetric analysis (TGA), a sample is continually weighted while heating, as an inert gas atmosphere is passed over it. Many solids undergo reactions that evolve gaseous byproducts. In TGA, these gaseous byproducts are removed and changes in the remaining mass of the sample are recorded.
