Linearity and non-linearity in DSC: A critique on modulated DSC☆

摘要: Abstract Recently a new interesting technique, modulated differential scanning calorimetry (MDSC), was published. This technique is based on Fourier transformation, and its sound applicability depends linearity in thermal processes, because the transformation or superposition principle. If process under observation non-linear process, physical meaning of should be closely examined. The DSC output signals some such as melting reaction, have been revealed to non-linear. Therefore, differentiation from non-linearity responses very important for DSC, they are discussed this paper. In discussion, methods analyze oscillating also proposed.
