- Determination of Cd, Ca, Pb, Au and Ag content by flame atomic absorption spectroscopy, in ores, concentrates and technological solutions;
- Qualitative phase analysis by X-ray powder diffraction of polycrystalline inorganic materials;
- Physical tests: petrographic examination for natural stone and aggregates;
- Metallographic tests: microscopic examination (metallography) for steels; determining the content of inclusions in steels; classification of graphite by visual analysis in cast iron; metallographic determination of the microstructure of sintered hard alloys; microscopic examination of welded joints of metallic materials.
