Thermogravimetric Analysis (TGA) is a technique used to measure the change in weight of a material as it is heated or cooled. This method helps scientists understand the thermal stability and composition of substances by observing how they lose mass at different temperatures. TGA is commonly used in materials science, chemistry, and pharmaceuticals. During a TGA experiment, a sample is placed on a balance inside a furnace. As the temperature increases, the weight loss can indicate processes such as evaporation, decomposition, or oxidation. The data obtained can provide valuable insights into the material's properties and behavior under heat.
