Differential Scanning Calorimetry:
In previous section we have studied DTA techniques in these methods, thermal reactions are observed by measuring the deviation of the sample temperature from that of the reference material. This deviation affects the DTA curve and decreases the sensitivity. Here is the another technique known as Differential Scanning Calorimetry (DSC) that have the advantage of keeping the sample and reference at the same temperature and heat flow into sample and reference is measured. This can be achieved by placing separate heating devices in the sample and reference chambers. This is in contrast to the DTA scheme, while both sample and reference are heated by the same source.
