2. DSC principle
When a system undergoes a transformation reaction under the effect of a heating or cooling program, its temperature evolves differently from that of a heat-inert material. Differential microcalorimetry measures the temperature difference (Δ T ) between the reacting material (sample e) and the inert material (reference r). This is proportional to the heat exchanged during the reaction:
with :
- Q :
-
quantity of heat exchanged (J)
- ΔT :
-
temperature difference (K)
