The heat capacity calibration constants of a commercial MTDSC instrument were determined in a variety of experimental conditions. For a given modulation frequency, the calibration constants are the same within a few percents for different temperatures and over a wide range of scan rates and modulation amplitudes. On the other hand, the modulation constants change substantially with the period. Rules to optimize the accuracy of the system are given.

Abstract
The heat capacity calibration constants of a commercial MTDSC instrument were determined in a variety of experimental conditions. For a given modulation frequency, the calibration constants are the same within a few percents for different temperatures and over a wide range of scan rates and modulation amplitudes. On the other hand, the modulation constants change substantially with the period. Rules to optimize the accuracy of the system are given.File in questo prodotto:
