Differential scanning calorimetry (DSC) Overview Polymers

Mettler STAR System DSC1

Method for measuring the enthalpy changes of a sample during heating, cooling or at constant temperature by means of Differential Scanning Calorimetry (DSC). The measurement method is capable of measuring both the temperatures at which the enthalpy changes occur and quantitatively their heat tones. The measurements can be performed in different gas atmospheres and with different heating or cooling rates.
