Thanks for the answer! So in this case, this specific peak intensity changing cannot indicate the concentration of this component change within the mixture, right? It's better to control the particle size in a certain lower size range, isn't it?
Yes, it's better if your particles are grounded down as finely as you can. In some cases, when samples are hard to grind (like fibers), one can also place the sample on a rotating stage, to physically randomize the orientation.
On the question of "mixture" -- You mentioned you have "one component" so unless something is degrading your material, and there is random orientation within the laser "scattering volume" (where the laser hits the material), you should have the same spectrum each time (of course, there will be the counting statistics error that always occur with scattering experiments).
sorry for the confusion. It's a two inorganic solid system, and during the measurement only one peak intensity of one of the components was fluctuating.
I see. That is a different problem. In that case, you would of course still want the particles to be ground down as finely as possible, and with random orientation. But what's even more important is how well mixed your two components are. If your composition is different from point to point, then the measured spectra would naturally differ as well.
