Hi,
I am trying to perform the SEM analysis of nano modified bitumen. The problem i am facing is how to dry out the sample stick to the stubs. I can't do that in oven as bitumen will melt down of it as the temperature will rise.
So, is there another way of drying it out?
Thank you
Dear Gohar Alam,
my suggestion is to use a critical point dryer. That should take away all water residues on your material. Alternatively you could try to put your sample under vacuum condition, so that the water desorbs slowly from your material.

Be sure you can easily contaminate, even badly contaminate, your SEM while observing bitumen.
@ Mark-Daniel Gerngross. Water is not a problem with bitumen, so do not expect any help from critical point dryer.
Dear Gohar Alam,
Please read this paper and you will find the useful information for your question.
