Mathematical studies of modulated differential scanning calorimetry - II. Kinetic and non-kinetic components
Further to Part I of this study (Vol. 325, pp. 101-109), this article describes the mathematical expression of MDSC by taking melting, crystallization as well as the temperature dependence of the heat capacity of a sample into consideration. A numerical method has been established and found to be suitable for the simulation of MDSC thermograms. It is found that a non-kinetic thermal event results in changes in the amplitude of heat flow of the thermogram of MDSC, but a kinetic thermal event causes no change in the amplitude of heat flow. A quantitative separation of the kinetic and non-kinetic components is, however, problematic since there is no linear relationship between the amplitude and the thermal parameters of a sample.
