The clear advantage of variable slit is to have more intensity at
medium/higher diffraction angles, compared to fixed slit systems adapted
to low starting angles. This is nice for quantitative Rietveld analysis
of samples having important intensities at low as well as at medium/high
angles, e.g
The only advantage I see with a variable slit is that you keep a
constant area on the surface. This
gives a constant sampling volume for samples that are thin compared to
the x-ray penetration depth.
In contrast, the sampling volume is fixed with a thick sample and
fixed slit for typical pow

I am seeking opinion on the installation of automated slits on a Panalytical MPD
Pros and cons.
Comments from a previous post are shown below by an esteemed colleague
I see little use for varable divergence slits for all sorts of reasons
(firstly as there is no rock solid conversion fr
