ADX-2500 X-ray Diffraction Instrument
Introduction
ADX-2500 X-ray Diffraction Instrument is designed for application in the microstructure measurement, testing and in-depth research investigations. With different accessories and the corresponding control and calculating software,ADX-2500 is a diffraction system according to the practical requirements in many fields. ADX-2500 X-ray Diffraction Instrument provides the structure analysis of single crystal, polycrystalline and amorphous sample.ADX-2500 is capable of the following: phase qualitative analysis and quantitative analysis (RIR, Internal standard calibration, External standard calibration, Additive criterion), pattern indexing, unit cell determination and refinement, crystallite size and strain determination, profile fitting and structure refinement, residual stress determination, texture analysis(ODF expresses three-dimensional pole figure), crystallinity estimate from peak areas, thin film analysis and others.
Features
Perfect incorporation of the hardware and software, allows ADX-2500 to perform different types of analysis for researchers from various fields; High precision of the diffraction angle measurement allows ADX-2500 to obtain the more accurate data; Higher stability of the X-ray generator control system provides excellent measurement accuracy; Simple and effective design makes ADX-2500 convenient for operation and user friendly.
Software
General diffraction data processing: automatic peak search, manual peak search, integral intensity, separation of Kα1, α2, background remove, pattern smoothing and magnifying, multiple plot, three-dimensional plot and simulation of XRD pattern. Profile fitting and overlapped peeks separation With the help of Pseudo-Voigt or Pearson-VII function, the overlapped peeks could be separated to determine the parameters of the peaks and calculate the crystallinity, crystallite size and strain. Qualitative Analysis The data processing software has the search and match function on the base of whole profile and diffraction angle. The profile matching procedure employs the designed mode to do the qualitative analysis by reducing the search range from major, minor, to micro phase without indicating the diffraction angle. The diffraction angle matching procedure is based on the peaks position and intensity and usually used for the qualitative analysis of the data with large angle error. Quantitative Analysis After the phase composition is determined, the content of each phase could be calculated with the help of RIR or/and the Rietveld refinement (Quantitative Analysis without criterion). Plot and Export The data processing software is operated with Windows interface. The preparing exported pattern could be labeled, zoomed in, zoomed out and also copied and pasted.
