Examples sample application requires a metal samples such as blocks, plates, round Zhu requires ground like a plane, an area of ??not less than 10X10 mm X-ray diffraction, can be used if the area is too small pieces pasted together. 2, for flaky, round Zhu shaped samples will serious preferred orientation, the diffraction intensity abnormalities. Therefore, a reasonable choice when the direction of the plane in response to requirements of the test. 3, for the measurement of microscopic samples of metal stress (lattice distortion), the measurement of residual austenite, requires that the sample can not simply kibble, a metallurgical sample preparation requirements, and general polishing or electrolytic polishing, eliminate surface strained layer. 4, ground to a powder sample request 320 mesh to about 40 microns. Low-intensity diffraction particle coarsening, poor peak shape, low resolution. To understand the physical and chemical properties of the sample, such as whether flammable, deliquescent Lincang X-ray diffractometer, corrosive, toxic, volatile. 5, the powder sample requires about 3 grams Puer X-ray diffractometer, if too little also need 5 mg. 6, the sample may be metal, nonmetal, organic and inorganic material powders. Determination of grain size and crystal lattice distortion of the polycrystalline material if no distortion is large enough, the powder diffraction pattern which theoretically should be particularly sharp lines, but in actual experiments, the line can not be seen. This is because the combined effect of factors and physical factors such as instrument, so that the pure diffraction line broadening. Pure lines determine the shape and width of the Diqing X-ray diffraction from an average grain size of the sample, the size distribution and the main crystal lattice defects, so the appropriate linear analysis, the nature of these factors can be obtained in principle and scales and other information. ? Trace detector test sample only 15mg, especially suitable for detection and analysis of criminal investigation, environmental, explosives, pipe corrosion and other difficult to collect samples.
