Analysis Report Excerpt
- The material of the microparticles is aluminum (impurities at a level of more than 0.4% by mass were not detected).
- In terms of chemical composition, appearance, morphological features, and geometric dimensions, the detected particles correspond to domestic aluminum powder (GOST 5494-95).
- Aluminum powder according to GOST 5494-95 is used as a pigment additive in the paint and varnish industry, for the production of aerated concrete at enterprises producing reinforced concrete building structures.
- Aluminum powder produced according to the specified GOST is not used in the industrial production of explosives and pyrotechnic compositions.
- All investigated swabs were evaporated to dryness and, together with the filters, were left for comparative studies.
CONCLUSION
- Trace amounts of hexogen and TNT - high explosives - were found in the swabs from the raincoat; trace amounts of TNT were found in the swabs from the cloth bag.
- Trace amounts of nitrate ions and ammonium ions, which could be part of ammonium nitrate, as well as particles of aluminum powder, were found on all specified objects.
- It is not possible to determine the source of origin of the nitrate ions and ammonium ions and unambiguously attribute them to explosive components for the reasons set forth in the research section.
- No fragments of explosive packaging were found on the objects.
- It is not possible to conduct comparative studies due to the lack of comparison materials and objects at the disposal of the experts.
