Muhammad Aamir Popular answer

Dear Shams,

It is highly recommended to do the EDX. You will get the information about the composition. You will know what the white and black regions are.

Another way is to find some literature, you will know if they have found nitrate in their SEM image and then compare your figure with that, and assign their references that your work is in consistent with them.
