Dear Pr. 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.
With best regards,Srihari. V "ఎందరో మహానుభావులు, అందరికీ వందనములు"

 Dear Rietveld users,

We are currently using transmission flat sample on our diffractometer. 
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.

Thank you very much in advance,
