Hi Scott,

Yes I have assumed the sample cross section area to be 1 sq. cm. and
then calculated the amount of sample required for that.

What i planned  is following :

I would calculate the amount of sample required for 1sq.cm area, take
that amount of sample and make it very fine paste using mortar and
pestle, and then apply it uniformly on a piece of kapton tape. Then fold
the tape over and over again in such a way that final bunch of tapes
will yield to 1 sq.cm. area containing the required amount of sample.

Will it be the right approach ?? OR I can take randomly few milligrams
of powder  (i.e. not strictly as per calculation) and  make a several
uniform layers of tape ??

With best regards,
Jatin

Hi Jatin,

I'm not sure I understand. If you have enough sample for the 1 square centimeter target, then there shouldn't be a problem, right? I was assuming from your initial question that you weren't going to have enough sample to do that.
