Differential Scanning Calorimetry (DSC) - Lab (E13)
 
Differential Scanning Calorimetry (DSC)
A differential scanning calorimeter (DSC) measures energy flow into (endothermic) or out of (exothermic) a specimen using a high sensitivity measuring head. The technique measures between room temperature and 1400o C under a flowing, inert gas the following properties: specific heat, melting temperatures, transition enthalpies, phase transformations, phase diagrams, crystallization temperatures, degree of crystallinity, glass transition temperatures, decomposition effects, reaction kinetics, and purity.
Samples can be powder, small pieces, or up to 5 mm diameter disks with a thickness of 3 mm.  Crucible materials are, graphite, platinum, or alumina.
