XRD • X-RAY POWDER DIFFRACTION ANALYSIS - IMR TEST
In XRD analysis, a focused X-Ray beam is shot at the sample at a specific angle of incidence. The X-Rays deflect or "diffract" in various ways depending on the crystal structure (inter-atomic distances) of the sample. The loions (angles) and intensities of the diffracted X-Rays are measured. Every compound has a unique diffraction pattern.
