X-ray Orientation Analyzer Alloy Test Notes

Posted by tongdaedith on Jun 5, 2019 in News

X-ray Orientation Analyzer in the analysis of alloying elements, trademarks, in order to ensure that the instrument is used normally, customers will supply a part of the sample for data analysis and proofreading.

Samples are even and clean

The sample supplied must be uniform, pure, and free of coatings, plating or oxide layers. If the surface layer of the sample contains these elements that are disturbing to the data effect, it is very simple that the detection effect is inaccurate.

Sample surface smoothness

The test surface of the sample should be flat and lubricated. Rugged surfaces can affect the accuracy of the analysis.

Detecting close range

There is no distance between the exploration window and the sample. There should be no gaps. When analyzing the sample, the X-ray orientation analyzer and sample should be stable and not shaken.

Sample repeat test

When analyzing smaller and thinner samples, be aware that there should be no other objects nearby, avoiding accidental detection of other substances. Causes an error in the effect. Conversely, for large metal samples, you should select a few more points and measure several times to get more accurate results.

Future Development Of X-ray Directional Analyzer

Posted by tongdaedith on Mai 15, 2019 in News

X-ray Orientation Analyzer has become an important part of the processing industry and surface engineering quality inspection, and is a necessary means for products to achieve superior quality standards. In order to internationalize the products, China’s export commodities and foreign-related projects have clear requirements. Triple ray protection software, hardware, and labyrinth design to ensure the radiation damage caused by the operator’s personal safety and accidental operation.

The large sample compartment design allows for more space in a smaller host than in conventional models. The X-ray directional analyzer adopts a new optical path design to minimize the negative influence of the air path on the measurement of chlorine, ensuring the detection limit and stability of chlorine. The latest optimized system analysis software can be based on sample material, shape and The size automatically sets the light pipe power, which can extend the service life of the light pipe and fully utilize the performance of the detector, greatly improving the measurement accuracy.

The most important application of the detector is to separate the isotopes and determine their atomic mass and relative abundance. The accuracy of determining atomic mass exceeds that of chemical measurement methods, and the exact mass of atoms above about 2/3 is determined by mass spectrometry. Due to the equivalent relationship between mass and energy, knowledge about the nuclear structure and nuclear binding energy can be obtained. For the analytical measurement of radioactive decay product elements that can be extracted from the ore, the geologic age of the ore can be determined. Mass spectrometry can also be used for organic chemical analysis, especially for trace impurity analysis, to measure the molecular weight of molecules. X-ray directional analyzers provide a reliable basis for determining the molecular formula and molecular structure of a compound. Since the compound has a unique mass spectrum like a fingerprint, the detector is also widely used in industrial production.

How To Better Analyze X-ray Orientation Analyzer

Posted by tongdaedith on Apr 29, 2019 in News

X-ray Orientation Analyzer is a modern instrument for the analysis of alloys and metal components. The development of human society can be said to be the continuous research on existing materials and the exploration of unknown substances, and the instruments such as X-ray directional analyzers. It is obvious that human beings have a microcosm of production and related research. Under the efforts of some manufacturers, people have obtained satisfactory feedback on how to conduct qualitative and quantitative analysis of X-ray directional analyzers.

First, qualitative analysis

The fluorescent X-rays of different elements have respective specific wavelengths, and thus the composition of the elements can be determined according to the wavelength of the fluorescent X-rays. In the case of a wavelength dispersion type spectrometer, for a crystal having a certain interplanar spacing, the wavelength λ of the X-ray can be obtained from the 2θ angle of the rotation of the detector, thereby determining the elemental composition. In fact, in qualitative analysis, the line can be automatically identified by computer and qualitative conclusions can be given. However, if the element content is too low or there is spectral line interference between the elements, manual identification is still required. First, the characteristic X-rays of the X-ray tube target and the accompanying lines of the strong peaks are identified, and then the remaining oblique lines are marked according to the 2θ angle. When analyzing the unknown spectral line, it is necessary to take into account the source and nature of the sample in order to make a comprehensive judgment.

Second, quantitative analysis

The quantitative analysis by the X-ray directional analyzer is based on the fact that the fluorescent X-ray intensity Ii of the element is proportional to the content Wi of the element in the sample: Ii=IsWi
In the formula, Is is the intensity of the fluorescent X-ray of the element when Wi=100%. According to the above formula, quantitative analysis can be performed by using a standard curve method, an incremental method, an internal standard method, or the like. However, these methods must make the composition of the standard sample as identical or similar to the composition of the sample, otherwise the matrix effect or the influence of the coexisting elements will cause great deviations in the measurement results.

In summary, manufacturers of X-ray directional analyzers have made a lot of efforts to determine the quality of products, so that products can be better qualitative and quantitative analysis, they will not only strive to praise each other to maintain core instrument manufacturing technology, but also to recruit The talents set up the R&D production team as the backbone of quality development. Finally, the X-ray directional analyzer will maintain good communication with customers and track actual experience feedback.

What Factors Will Cause Errors In The X-ray Orientation Analyzer?

Posted by tongdaedith on Apr 17, 2019 in News

The X-ray Orientation Analyzer tablet is not smooth, resulting in a non-smooth analytical surface that affects the measurement results.

The vacuum degree of the optical path is not suitable, and the spectroscopic crystal and the filter are not selected well, which causes interference of various rays and affects the analysis.

The X-ray tube voltage and current are unstable, resulting in fluctuations in the results.

Over time, the positional change of the internal component size of the X-ray directional analyzer causes a change in the intensity of the primary X-ray, or a scar on the anode of the X-ray tube, and the target element is deposited in the window, causing an error in the analysis result.

The change in temperature causes a change in the interplanar spacing of the spectroscopic crystals, thereby affecting the spectral efficiency. It is proportional to the high-pressure drift of the counter tube, and the temperature change causes the gas composition in the tube to change, affecting the magnification.

The drift of the electronic circuit, the statistical error of the counting, the counting error introduced by the time loss of the detection process, and the like.

Changes in the temperature of the gas, nitrogen, methane gas flow, temperature, etc., will affect the absorption of the X-ray directional analyzer by the gas in the optical path. Therefore, once the pressure reducing valve of the cylinder is adjusted, do not move it at will, especially when replacing the new gas, you must try to adjust the air pressure several times. Otherwise, the airflow and air pressure are unstable, resulting in errors.

X-ray Orientation Analyzer Helps To Understand The Substance

Posted by tongdaedith on Apr 10, 2019 in News

X-ray Orientation Analyzer uses X-ray diffraction principle to quickly determine the cutting angle of natural and artificial single crystals (piezoelectric crystals, optical crystals, laser crystals, semiconductor crystals), and can be used for the above-mentioned single crystal directional cutting with the cutting machine. An instrument that is indispensable for processing crystal devices. The instrument is widely used in the research, processing and manufacturing of single crystal materials.

The high voltage generated by the high voltage transformer is applied to the X-ray tube to generate X-rays, and the X-ray directional analyzer is irradiated onto the sample. When the formula is n = 2dsin, diffraction is generated, and the diffraction line is received by the counting tube, and the microampere meter passing through the amplifier When it is displayed, when the monochromator is used, the diffraction line is monochromated, received by the counter, and displayed by the microampere meter of the amplifier, so that the measurement accuracy can be improved.

X-ray single crystal directional diffraction is an important method for determining the crystal structure of proteins. Biomacromolecule X-ray crystallography is the science that reveals the structure and function of molecules. There is currently no tool that can directly observe the arrangement of atoms and groups inside a protein. Although the electron microscope is close to seeing the outline of the macromolecule. However, it is still limited to revealing the size, shape, symmetry, and aggregation state of the molecules. The spatial structure of protein crystals can be indirectly studied by X-ray single crystal directional diffraction. Research on crystal structure will help people understand matter at the atomic level.

The Role Of X-ray Orientation Analyzer

Posted by tongdaedith on Apr 3, 2019 in News

X-ray Orientation Analyzer features
1 penetration
X-ray flaw detectors can penetrate substances that are not transparent to visible light. The strength of its penetration is related to the wavelength of the x-ray and the density and thickness of the material being penetrated. The shorter the x-ray wavelength, the greater the penetrating power; the lower the density, the thinner the thickness, the easier the x-ray will penetrate. In actual work, the penetration of the x-ray (ie, the mass of the x-ray) is determined by the magnitude of the voltage volt (kV) of the bulb, and the product of the current (mA) through the x-ray per unit time and time is multiplied by time. Represents the amount of x-rays.
2 ionization
When x-rays or other rays (such as gamma rays) are absorbed by a substance, the molecules constituting the substance are decomposed into positive and negative ions, which are called ionization, and the amount of ions is proportional to the amount of X-rays absorbed by the substance. The amount of x-rays can be calculated by measuring the degree of ionization by means of air or other substances. It is the detection equipment that detects the flaw detection of the part. X-rays have other effects, such as sensitization and fluorescence.
