Differential scanning calorimetry:
Information about the DSC curves:
In general, the result of a DSC experiment is a curve of heat flux versus temperature or versus time. This curve can be used to calculate enthalpies of transitions, i.e., ΔH = kA (where, H is the enthalpy of transition, k is the calorimetric constant, and A is the area under the curve) , which is done by integrating the peak corresponding to a given transition.
The value of k is typically given by the manufacturer for an instrument or can generally be determined by analyzing a well-characterized sample with known enthalpies of transition.
Applications of DSC:
DSC technique can be used to obtain glass transition, melting points, crystallization times and temperatures, heats of melting and crystallization, percentage of crystallinity, oxidative stabilities, heat capacity, completeness of cure, purities, thermal stabilities, polymorphism, recyclates or regrinds
