enables you to rapidly identify crystalline substances by reflecting X-rays from powderized materials. The angles at which the diffracted X-rays can be recorded (= diffraction pattern) allow for the identification of the substances. In addition, the crystalline modification of the substance, its composition, the symmetry and the lattice constants of the crystals become accessible. Anton Paar provides attachments for these investigations at non-ambient temperatures (-190°C to 2300°C) and under various atmospheres.
Small-angle X-ray scattering (SAXS)
is the method of choice when the structures of two-component systems (colloids) have to be investigated. X-rays are scattered into all directions when they penetrate matter with inhomogeneities (nano-particles) and especially towards small angles when the particles are large compared to the wavelength of the X-rays. The resulting scattering patterns are indicative of the shape and the size of these inhomogeneities. The surface-to-volume ratio of the internal structure of the materials can also be determined from this. With the SAXSess system, Anton Paar provides a state-of-the-art instrument for investigating nano-structured liquids and solid-film samples between -150°C and 300°C.
