Summary of Technique

  • Simultaneous DSC-TGA measures both heat flow and weight changes in a material as a function of temperature or time in a controlled atmosphere.
  • Simultaneous measurement of these two material properties not only improves productivity but also simplifies interpretation of the results.
  • The complimentary information (DSC & TGA obtained allows differentiation between endothermic and exothermic events which have no associated weight loss (e.g., melting and crystallization) and those which involve a weight loss (e.g., degradation).
