Hello,
I have performed DSC for my pure pigment sample and pigment mixed with PVA but, there is no peak observed in the graph. Samples were dried well and there was one heating cycle from 30 to 250 degrees. Kindly share your thoughts on the possible reasons for that.
Thank you

Hi Mandeep Gulati
Your PVA may be amorphous, in which case you will not see a PVA-derived peak. You may or may not see a glass transition (partly depending on heating rate - easier to see it at fast heating rate). As for the pigment, many pigments don't have any solid-state phase transition in your range of temperature. Do you know that your pigment is supposed to show a phase transition?
