Comparison Between Modulated Differential Scanning Calorimetry (MDSC) and Dynamic Differential Scanning Calorimetry (DDSC)


Both modulated differential scanning calorimetry (MDSC) and dynamic differential scanning calorimetry (DDSC) are registered tradenames for instrumental techniques which are part of the temperature-modulated differential scanning calorimetry (TMDSC) family. Both oscillate their input ramps differently in that the MDSC uses a sine wave while DDSC generates a sawtooth wave. Although we have found similarities between both techniques we do note some differences. These differences primarily occur in the melting reversing signal for the same conditions and as one changes period and amplitude. These differences may be ascribed to the different time response as noted between a heat flux and power compensation DSC.
