Differential Scanning Calorimetry (DSC) Testing Service
Differential Scanning Calorimetry (DSC) is a thermoanalytical tool used to monitor changes in a material's heat capacity as a function of temperature. For a DSC study, the sample holder's temperature should rise linearly as a function of time according to the temperature programme typically used for the study. Over the temperature range that will be scanned, the reference sample should have a clearly defined heat capacity.
