These devices are sold commercially as attachments to standard powder diffractometers. The attachment normally consists of a long soller slit assembly and a flat crystal monochromator.
WebNow with grazing incidence X-ray diffraction, you can focus on the surface of your samples and more effectively measure the crystallographic properties of thin films and coatings. Figure 1: Enjoy a truly versatile powder diffraction capability in a compact state-of-the-art instrument Aeris WebThe principles of grazing incidence X-ray diffraction (GIXD) are discussed. A sample of a crystalline material is composed of a surface region including its top layer and a bulk part. The effect of the surface region on the intensity of surface X-ray diffraction cannot be generally disregarded.
WebX-ray diffraction (XRD) is a non-destructive technique for analyzing the structure of materials, primarily at the atomic or molecular level. It works best for materials that are crystalline or partially crystalline (i.e., that have periodic structural order) but is also used to study non-crystalline materials.
