Angstrom Advanced 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;

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.

Angstrom Advanced Nitrogen Generating Plant by Membrane Separation

Introduction
The compressed air compressor filter into the polymer membrane filters, a variety of gas in the film in the solubility and proliferation of different factors, leading to different gases in the membrane penetration rate in a relatively different. According to the characteristics, various gases can be divided into "rapid gas" and "slow gas". After being compacted and purified (to remove oil, water and dust) the air will enter the membrane separation to separate. First, the O2, CO2 and some vapor will infiltrate into the membrane wall and then exit through the discharge port by air pressure; since the infiltrating speed of N2 is slower, it will flow out from the gas collector at the end of the pressure box and finally enter nitrogen buffer tank.
