- The qualitative phase composition with the X-ray diffraction method for solid polycrystalline samples and in the pulverulent form with the possibility to determine the percentage share of the crystalline and amorphous phase in a sample.
- The quantitative phase composition with the Rietveld’s method or internal pattern method within the range of 5 – 100%.
- Determining of the crystalline texture with the X-ray diffraction method.
- Phase identification and identity confirmation for samples of the pharmaceutical origin – active and auxiliary substances.
- Measurements and determining of crystalline structures of monocrystalline samples within the temperature range of 80 – 500K.
- Measurements of thin layers and epitaxial layers – reflection curves from symmetric and asymmetric planes, determining of the grid node maps reversed from the symmetric and asymmetric planes.
- Grinding of rock, soil particles in a ball mill.
