Thermogravimetric Analysis (TGA) is the analysis of dimensional changes of a material as a function of temperature. ARDL provides testing to measure these changes as they relate to the linear thermal expansion of a material using specific equipment and test methodologies. Measurements are made of the material’s weight loss percentage over a temperature sweep. Analysis of the results can help with understanding the sample’s composition, the amount of highly volatile matter, medium volatile matter, combustible material and ash content, as well as its thermal stability. Test temperatures are usually room temperature to 1,000°C.
