Each diffractometer is dedicated to some characterization technic, although their looks are almost identical, and they could measure the same thing.
There is some info you can see as useful.
Diffraction
An important part of the characterization of material in the laboratory is the study of the crystalline structure by X-ray diffraction, aka X-ray scattering. Our laboratory has two diffractometers, one is dedicated to X-ray powder diffraction, and the second is to measuring the thin layers.
