Portable X-ray diffractometer  "RIKOR-6"    (on the basis of capillary optics)

X-RAY DIFFRACTOMETER "RIKOR-6" for the study of structural and elemental composition of inorganic materials of all shapes and sizes

 

     

APPLICATIONS:

 
- Microelectronics (ferro-piezoelectric ceramics, ferrites, films, electrolytic    coatings, semiconductors).
- Metallurgy (structure of rolled composites)
- Engineering (recrystallization as a result of processing, hardening coating, welded joints).
- Geology and mining.
- Chemicals.
- Fertilizer production
- Cement Industry.
- Ecology.
- Archeology and restoration.
- Production and study of special materials (cermets, high temperature materials and high pressure)
- Study of crystallization, phase transformations in research laboratories and industrial environments.
- Dynamic study of the impact of various factors - such as temperature, pressure, radiation.

 

The X-ray diffractometer "RIKOR-6" is designed for structural and elemental analysis of powder and liquid samples, as well as large parts. Functionally the x-ray diffractometer combined with energy dispersive spectrometer channel that provides information, as on the elemental composition and the structure of the sample.

 

Features of X-ray diffractometer "RIKOR-6"


- The new portable diffractometer combined with the x-ray fluorescence spectrometer
- Portability
- The lack of movement while shooting
- Simultaneous recording of a broad section of the spectrum
- Expressive evaluation
- Radiation Safety
- Ease of maintenance and operation
- Allows you to analyze powders, liquids, samples of any shape, large parts
- Minimal or no sample preparation
- High resolution detectors
- The system optical alignment and determining the place of analysis
- Two-wave (2 X-ray. Tube) diffractometer, with no additional tuning of the transition from one type of radiation to another.

 

The use of capillary half - lens in X-ray diffractometer "RIKOR-6"   allows you to create a spatially collimated (both horizontally and vertically) X-ray radiation with a divergence ~ 3 * 10-3 rad, increase the area of the flow of quasi -parallel x-ray beams from the source to the sample. Peculiarity of X-ray Kumahov's half-lens  is to capture X-ray emission from the focus of X-ray tube (linear or fine-focus) and its transport throw specific capillary channels. At the downstream of half - lens each separate channel is a source of X-rays. Thus, the output of half-lens essentially have a lot of microfocus sources, there is a division of linear or fine- focus spot in microfocus sources. Focal spot size can vary depending on the size of capillaries from a few to hundreds of microns.

 

Thanks polycapillary optics


Collimation-dimensional geometry of the parallel beam is ideal for general analysis
Great capture angle - the intensification
Adjusting geometric form of the x-ray beam
  No defocusing
No displacement of the sample: it provides a good and a definite phase analysis
Permanent form of the peak improves the accuracy of the analysis of the structure

UNIT - LAYOUT

X-ray tube in this x-ray diffractometer with air cooling does not require a complex system of water cooling. The unit of radiation is safe at a distance of 20 cm
    Register spectrum of samples carried out at fixed positions of the radiation source and a position-sensitive detector. Simultaneous collection of the spectrum in the angular range 55 can significantly speed up the analysis of the objects of study and record the rapid processes.
     The size of the diffraction spots on the sample -  2mm to 0,2 mm, place the X-ray beam exposure is fixed with the help of an optical system for aligning, i.e. the device can be used as micro-diffractometer
     To increase the resolution of the device and reduce the background in this x-ray diffractometer, designed filter unit ahead of the detector. All sections of the diffraction space are measured with the same resolution

Application of a filter unit in this x-ray diffractometer increases the resolution of close peaks, provides filtering of radiation, increases the ratio of peak / background of four times, improve accuracy of the angular position of diffraction peak

SOFTWARE OF X-RAY DIFFRACTOMETER "RIKOR-6"

Allows you to handle the resulting spectrum with the definition of the situation, the intensity and width of the diffraction peaks, separated superimposed diffraction peaks, subtract background, to smooth the spectrum, to view a series of captured samples

Phase analysis of the studied samples is carried out using the search engine with a large selection of identity-based criteria for the use of databases of polycrystalline materials.

 

Energy dispersive x-ray spectrometer channel allows for qualitative and quantitative analysis of chemical elements contained in the sample. You can analyze elements from Al13 up to U92. The range of concentrations: 50 g / tonne (ppm) to 100%.
