Differential Scanning Calorimeter


Differential scanning calorimetry is used to study changes in enthalpy as a material is heated. It determines the temperatures of thermal events, such as the following, to be accurately determined.

  • Glass transition temperatures of polymers
  • Melting points
  • Phase transformations
  • Curie point transitions
  • Reactions (including decomposition, devolatilization, crosslinking, etc.)

The heat liberated or consumed during these events, such as heat of fusion and heats of reaction, can also be accurately determined, as can specific heat capacity. These parameters are very useful in the design of heat treatment schedules as well as insulation/heating power requirements for processes.

Touchstone’s Perkin Elmer differential scanning calorimeter can be run under inert or oxidizing atmospheres at ambient pressure. Its upper temperature limit is 727 deg C.
