High Temperature Differential Scanning Calorimeter

Differential Scanning Calorimeter

The high temperature Differential Scanning Calorimeter (DSC) from Netzsch is designed to measure thermal energy events from room temperature to 1400 °C. The instrument is capable of quantitative and qualitative measurements and can run in several gas environments.

Sample materials are held in crucibles made of alumina, graphite or platinum depending on the sample composition and reactvity. A crucible containing the sample and an inert reference crucible are then placed in the instrument chamber, on a platforms connected by a thermocouple. Tests are performed in a shared environment and thermodynamic properties of the sample material can be calculated by comparison..

Measurable Properties

  • Specific Heat (aka Heat Capacity or Cp) as a function of temperature
  • Transition Enthalpy (aka Latent Heat) for melting and other phase changes
  • Temperatures of Melting & Phase Transformations
  • Temperature and energy change of Glass Transition & Crystallization

Calibration

The instrument is calibrated with a series of high purity metals. Calibration curves are verified every 3 months, as needed. Sapphire standards are also available for users.
