Thermal Analysis

Thermal analysis is a branch of materials science where the properties of materials are studied as they change with temperature. Several methods are commonly used - these are distinguished from one another by the property which is measured:

  • Differential thermal analysis (DTA): temperature difference
  • Differential scanning calorimetry (DSC): heat difference
  • Thermogravimetric analysis (TGA): mass
  • Thermomechanical analysis (TMA): dimension
  • Dilatometry (DIL): volume / dimension
  • Evolved gas analysis (EGA): gaseous decomposition products
  • Laser / Xenon Flash (LFA): thermal conductivity, thermal diffusivity
  • Seebeck Coefficient / Electric Resistivity

Furthermore thermal imaging techniques are commonly used in Research & Development and product/process testing environments, where accuracy and reliability are vitally important. IR cameras are used for capturing and recording thermal distribution and variations in real time, allowing engineers to see and accurately measure heat patterns, dissipation, leakage and other temperature factors in equipment, products and processes.
