DSC TGA Contract Testing

These are quick cost effective screening tests. The Differential Scanning Calorimeter (DSC) measures the heat flow to or from the sample under heating and can be used to determine enthalpy changes. Thermogravimetric analysis (TGA) measures the mass loss from a sample (in µg) as a function of temperature and can be used to pinpoint temperatures of phase changes and reactions.

The DSC is used for various ASTM tests including: 

  • E 537-0: Standard Method for Assessing the Thermal Stability of Chemicals by Methods of Differential Thermal Analysis
  • E 698-99: Standard Test Method for Arrhenius Kinetic Constants for Thermally Unstable Materials
  • E1952-06 Standard Test Method for Thermal Conductivity and Thermal Diffusivity by Modulated Temperature Differential Scanning Calorimetry
  • E1269-05 Standard Test Method for Determining Specific Heat Capacity by Differential Scanning Calorimetry
  • E 793-01: Standard Test Method for Heats of Fusion and Crystallization by Differential Scanning Calorimetry
  • E 794-98: Standard Method for Melting and Crystallization Temperature by Thermal Analysis
  • E 928-96: Standard Test Method for Determination of Purity by Differential Scanning Calorimetry

The TGA can be used for various forms of analyses including:

  • Determining the decomposition temperature and kinetics of single and multi-component systems
  • Estimation of material lifetime and for the thermal endurance of a material
  • Compositional analysis of a sample and material loss on drying.
