Differential Scanning Calorimetry measures the heat flow into and out of a material as a function of time or temperature. This technique can be used to characterize thermal transitions and chemical reactions. Modulated DSC is an additional option that allows the separation of reversing phenomena (Tg, melting, etc.) from non-reversing events (volatilization, curing, etc.) in a single test. Problems or applications that could not be solved by regular DSC because of interfering events can now be better understood using modulated DSC.
Common uses of DSC include:
• Glass transition temperature (Tg)
• Melting points
• Crystallization
• Heats of fusion and reaction
• Specific heat and heat capacity
• Rate of cure
• Reaction kinetics
• Purity
