Summary

The definition and comparison of the elemental composition of micro-particles of various origins is usually one of the mandatory research stages in many areas of forensic examination of materials, substances and products.

Taking into account the small amount of substance in micro-particles and the need for them to at least partially preserve the widely used methods of atomic emission, absorption, X-ray fluorescence spectroscopy for further studies, it often turns out to be ineffective or inappropriate.

The study of the experience of the physicochemical laboratories of the world’s leading research institutes forensic expertise confirms that the best way to study microscopic particles is to scan electron microscopy with X-ray fluorescence microanalysis (SEM-EDS).

The possibilities of using SEM-EDS in expert research of micro-particles on a number of practical examples (shot products, toners of printing devices, inorganic phosphors, inserts in jewelry) are considered as well. These methodological approaches can be adapted to study the elemental composition of almost for any micro-particles containing inorganic components.
