Are these from two heating and cooling cycles on the DSC? What were the cycles that were run?

Dear Salma Salem

At first, you have to choose second heating and first cooling heat flow curves in your instrument's software. Then, click Calc option and select peak area. You will see a new windo and then select the options which you need. To calculate heat flow, select the areas with cross marks and then click calculate. Like your curves, you can see every parameters and describe accordingly.
