Dear Baskaran Kuppan ,

DSC is a technique that measures the changes of heat flow of a sample, as a function of temperature, either when heating the sample, or when cooling the sample. From a typical DSC, you can see either peaks (that go up or down), or changes in the baseline of the curve.

Each peak is usually related to some heat release (exothermic peak) or some heat absorption (endothermic peak). Then, every process that your sample can suffer when heating or cooling may be related to these peaks. In order to elucidate that, you will need to seek for bibliography of some related samples.

Let me tell you an example: the fusion of crystals from a solid thermosetting polymer (benzoxazines for example), is usually an endothermic process, so normally, an endothermic peak is seen at low temperatures, meaning that the crystals of the polymer are under a fusion process. At higher temperatures, the polymerization of this type of polymers is exothermic, thus, an exothermic peak can be seen at high temperatures. In a DSC graph, one peak goes up and the other goes down. Also, if you are lucky, the Tg of some polymers can also be seen as a change in the baseline of the DSC.

Maybe you can look for other biomass DSC in order to compare your results.

Best of luck!
