Dear Rietveld Users,
I would like to find a standard in transmission geometry in order to
test the resolution of our futur laboratory diffractometer.
I would like to find a simple coumpound with a relative low absorption
from 10 to 20 cm-1 with copper radiation.
I have asked the same question 10 years ago, the answer was some diamond
and LiF.
Now I would like to found some organic compound easy to find and cheap
with the lowest FWHM.
From the paper involved in the structural determination from powder
diffraction data : Solving molecular structure from laboratory X-ray
powder diffraction with DASH, the minimum FWHM was 0.080°.
In comparison in reflection mode the lowest FWHM is approximatively
0.040°with LaB6 or a good alumina with any laboratory high resolution
diffractometer.
If anyone has an idea.
Thanks in advance,
Best Whishes
