Differential Scanning Calorimetry (DSC)

This is a technique which examines the amount of heat required to increase the temperature of a sample relative to a reference. The technique relies on the fact that as the sample undergoes various physical transformations, more or less heat will need to flow to it than the reference to maintain both at the same temperature. The resultant data gives information of crystallinity (an exothermic process) and melt temperature, the enthalpies of which can also be determined. It can also be used to give the glass transition temperature of a material and also any other relaxations the material may undergo in advance of this.
