Advantages of DSC:

1. Small sample size 1 to 10 mg.

2. Easy and rapid procedure of analysis, classically 15 to 30 min. per determination.

3. Ideal for comparison of sample purity for instance within quality control.

4. Does not need high absolute temperature accuracy (within contrast along with melting point depression method.

5. Does not require calibration with known impurity levels, cryoscopic constant are obtained simultaneously.

6. The use of melting rather  than a freezing  curve prevent  problems  related with  super cooling of sample , poor crystallizability from melt , instability within the  melt etc.
