Thermal Gravimetric Analyser
Thermal Gravimetric Analysis is widely applied for the measurement of a material's mass loss at elevated temperatures.
Thermal gravimetric analysis (TGA) is a method of thermal analysis in which the mass of a sample is measured over time as the temperature changes. The instrument continuously monitors the weight change that occurs as a sample is heated at a constant rate. As the temperature increases, various components of the sample are decomposed, and the weight percentage of each resulting mass change can be measured.
TGA measurement can be used to determine a material’s thermal stability and its fraction of volatile components by providing information about physical phenomena, such as phase transitions, absorption, adsorption and desorption, as well as chemical phenomena including chemisorption, thermal decomposition, and solid-gas reactions.
TGA may also be hyphenated with GCMS to perform more advanced analysis such as volatile gas, decomposition by-products and reactions.
