Introduction Differential Scanning Calorimetry (DSC), as a fast and reliable means of analysis, is gaining more and more applications, not only in material development but also in quality assurance, raw material control and failure analysis. Due to the increasingly complicated material structure, the sensitivity and resolution of the instrument put forward high requirements. At the same time, due to streamlining the actual conditions of the employees, the ease of operation of the instrument and the self-
