Differential Scanning Calorimetry (DSC) involves measuring the temperature difference between the sample and a reference material (a thermally inert material). Very often it is done in parallel with the measurement of mass change using temperature thermogravimetry analysis (TGA).
Properties characterized by the techniques include melting, crystallization, glass transitions, cross-linking, oxidation, decomposition, volatilization. The results are widely used in quality assurance; root cause analysis and life-time predictions. The techniques are often complimented by:
