Dear Chuisy,
The broad bump you are experiencing at low angle may be to do with the
slits. One has to be careful with these new XRD machines which have
variable slits, to make sure the divergent and the anti-scattering slits
are equal and if you choose to keep the slits fixed, which usually
Hi,
Looking at the attached file, my opinion is that this effect is caused by a
quite large divergent (or both divergent and anti-scattering) slits. It is
not normal to have over 1000 counts at 5 degrees 2-theta. This could be due
either by a portion of incident beam or by a scattering from the
Dear William,
Thank you for your kind suggestion.
Well, our XRD is not a very new model, we use a fixed divergent slit, receving
slit and antiscattering slits. But I need to check them whether the divergent
and anti-scattering slits are in the same sizes. When I added the anti-scatter
slit, the
Dear Stephen,
I apologise for calling you chuisy last time round.
One suggest to test the size of the footprint is, I think, to use common
rock salt. Grind this up and place liberally over your plate and you can
check at low angle where the X-rays are striking the plate, because the
salt will go
