The main areas of activity of the Analytical Center (AC) of the FORC RAS are studies of the chemical composition and structure of materials at the macro-, micro-, and nano-levels, including:

• Determination of chemical composition and impurity content by energy-dispersive X-ray microanalysis for various classes of materials, including nanomaterials
• Characterization of the distribution of elements (from B to U) in different areas of the material
• Phase determination, mapping of crystal orientations of grains, study of grain boundaries by electron backscatter diffraction
• Obtaining microscopic images in electron beams in various modes, including in low vacuum mode, to characterize the surface properties of materials
• Study of the phase composition and structure of samples by X-ray methods diffractometry

The objects of research are:

• photonic crystal-based light guides and special fiber light guides;
• new materials for fiber optics, quantum electronics, and other areas of modern science and technology;
• nanomaterials and nanocrystalline inclusions in materials;
• single crystals and composites;
• cultural heritage objects

The Analytical Center conducts research on the topics of the General Physics Institute of the Russian Academy of Sciences and collaborates with a number of institutes of the Russian Academy of Sciences, universities, colleges, industrial enterprises, and firms. The Analytical Center is part of the Shared Use Center "Analytical Center of the General Physics Institute of the Russian Academy of Sciences." The AC services are presented on the CSEU website (https://www.gpi.ru/sci/cseu/)
