Differential scanning calorimeter
Hence, based on this simple model it turns out that there is a direct proportionality(K) between the heat flow and the temperature variations of the sample. This proportionality constant is dependent on the distance from the wall to the sample shown as (Δx), the cross section area of the support (A) and the thermal conductivity (k). Generally, the main results of the DSC experiment is an output signal of heat flow rate as a function of temperature, which are called DSC curves . Analysis of these curves plays an important role in determination of heat of transformation, heat of reactions or any changes in heat capacity due to temperature variations, for instance, the enthalpy of exothermic and endothermic processes can be determined by finding the area under the DSC curve using a mathematical technique called integral calculus.
