Hello Rietvelders,
I propose that you could secure powder in a thin layer on a single piece of kapton or other substrate using dilute collodion or vacseal. I find that both work best when diluted quite a bit. Collodion will sometimes peel off of its substrate, while vacseal does not (remains sticky) and can be dissolved in acetone. I haven't personally done transmission, I just know that those two materials can be very helpful :) best of luck!

Francois GOUTENOIRE, In case of kapton tape there is a chance of getting diffraction peak at low angle, I prefer to use magic scotch tape. Some times to avoid the background from this tape as well, I use small punch in the thick paper card and pack the material in that hole for transmission XRD, this I find better than any thing else.

To prepare the transmission flat sample we are using mylar 15microns or kapton. We put the sample between 2 mylar foils. I would like to know if there is some tricks in order to nicely put the powder in the center of the circular sample older and if there is also some tricks in order to avoid electrostatic problems.
