X-RAY Apparatus for Analysis
X-ray diffraction System
X-ray diffraction (XRD) is a non-destructive technique for the qualitative and
quantitative analysis of the crystalline materials, in form of powder or solid.
Basically XRD is obtained as the "reflection" of an X-ray beam from a family of
parallel and equally spaced atomic planes, following the Bragg's law: when a
monochromatic X-ray beam with wavelenght λ is incident on lattice planes with an
angle q , diffraction occurs if the path of rays reflected by successive planes
(with distance d) is a multiple of the wavelenght λ is the wavelenght of the
radiation coming from the X-ray tube. With a Goniometer, it is possible to
analyze the d spacing of a crystal (or a powder) by measuring the first-order
angles of diffraction

The new dimension in X-ray diffraction
|
The HRD 3000 high resolution diffraction system incorporates the most advanced digital electronics, computers and Microsoft’s Windows 98/ME operating system. Exact angular positions of the goniometer circles are guaranteed by a well-devised combination of stepping motors and optical encoders. The goniometer circles are positioned at high speed. The HRD 3000 diffractometer system can be used on a wide range of analytical problems, from texture
to thin film analysis, strain measurements and reflectometry. With this high performance, high resolution diffractometer, you can obtain outstanding results with amazing ease, when determining layer thickness and composition in semiconductors. The high resolution reflectometry studies can be performed with the HRD 3000 to characterise layer thickness, density, surface and interface roughness. Seven independent degrees of movement freedom, allowing every possible sample position. The
high efficiency of the various components permits analytical results of high quality. Different kind of source and optical components, several detectors and special attachments can be added to meet all your requirements. You have the choice of a large number easily mounted components. For more information on our system, attachments, and custom design accessories, contact us directly. Powerful, user-friendly software makes measurement easier than ever and includes many
sophisticated features to aid in the interpretation of the results.

Another approach to X-ray diffraction
| |
Many scientist are studying phase transitions of materials, in order to understand their properties. Other physical methods can be used, but only diffraction is able to provide information on the global structure of the compound. One common problem is the control, during the acquisition time, of
phase changes in the sample. Using X-RED 3000, from the beginning of the run, the user can visualised the entire diffractogram, practically in real time; so that a sample evolution is immediately visible.
The X-RED 3000 offers solutions for a wide range of analytical problems, from routine qualitative and quantitative analysis, to residual-stress analysis, non-ambient analyses, retained austenite quantification, crystallite size/lattice strain and crystallinity calculations, phase
transitions and transformations, kinetics & non-equilibrium phenomena.
