TGA, or Thermogravimetric Analysis
TGA, or Thermogravimetric Analysis, is an analytical technique used to study the thermal properties of materials by measuring changes in their weight as a function of temperature (or time) in a controlled atmosphere. TGA provides valuable information about the composition, thermal stability, decomposition kinetics, and other properties of substances. It is widely used in material science, chemistry, and various industries, including polymers, pharmaceuticals, and environmental analysis.
TGA analysis provides several key pieces of information, including:
Thermal Decomposition: The temperature(s) at which a substance decomposes or loses weight due to thermal processes.
Rate of Decomposition: The rate at which weight loss occurs during thermal decomposition, which can provide insights into the kinetics of the reaction.
Residue Analysis: The identification and quantification of the residue (or ash) left behind after thermal decomposition.
Evaluation of Material Properties: TGA can be used to assess the composition, purity, and thermal stability of materials, including polymers, pharmaceuticals, catalysts, and more.
Moisture Content: TGA is often used to determine the moisture content of materials by measuring weight loss upon heating.
