X-Ray Diffractometer (XRD)
DESCRIPTION
X’Pert MRD diffractomer from PANalytical with Euler cradle. Ideal for measurement of residual stresses and crystallographic texture. Horizontal diffactometer with both Bragg-Brentano and parallel beam optics. Max. weight 500 g, max. height 24 mm. Two radiations available, Cu and Cr. Possibility of thin films characterization by Grazing Incidence X-Ray Diffraction. Software HIGH SCORE for phase identification; STRESS and TEXTURE for residual stresses and texture analysis, respectively. Indispensable technique for analysis and characterization of a wide range of materials.
MOST OUTSTANDING EQUIPMENT AND COMPONENTS
BRUKER D8 ADVANCE A25 X-ray diffraction equipmentBRUKER D8 ADVANCE A25 X-ray diffraction equipment. It has a radius that can vary from 250 to 300 mm and allows working in reflection and transmission mode. It has several sample holder platforms: XYZ table completely controlled by software that allows the exact positioning of the sample or its mapping by means of the X-ray beam; Euler cradle (goniometer) that allows not only the rotation around the diffractometer axis, but also around the two axes perpendicular to it, making it ideal for the measurement of crystallographic textures and residual stresses by the PSI or side-inclination method; and platform with monitored rotation that allows working in reflection and transmission modes. The primary optics allow work in both Bragg-Brentano with automatic variable divergence slit and parallel beam, the latter including a Göbel mirror for Cu Ka radiation and a polycapillary module that works with the most common X-ray radiation, ideal for the measurement of textures and residual stresses. It has an ultra-fast 0D/1D LYNXEYE XE-T detector with dispersive energies and high resolution that eliminates fluorescence and kb radiation, and acts as a diffracted beam monochromator. It has Cu, Co and Cr radiation and is used for phase identification and quantification as well as for residual stress measurements, crystallographic textures and phase analysis in thin films by grazing angle.
Parallel beam optics (pollicapilar lens, parallel plate collimator, graphite flat monochromator). Small angle slits for Grazing Incidence X-Ray Diffraction.
