Total scattering or pair distribution function analysis (PDF) is an analytical technique that provides structural information from disordered materials by using the complete powder XRD pattern (Bragg scattering from long-range order and diffuse scattering from local structure). Typical materials can be amorphous, poorly crystalline, nano-crystalline or nano-structured. Examples of samples are:
The Materials Research Laboratory has recently acquired a Mo X-ray source Panalytical Empyrean X-ray diffratometer capable of performing X-ray total scattering measurements. The new Empyrean has a 3kW Mo X-ray source with focusing optic, transmission capillary spinner stage with alignment camera, and Galipix 3D CdTe area detector (100% efficient for Mo radiation) that is optimized for rapid PDF measurements.
