Analyse médico-légale des résidus de tir
Reconstituez les scènes de crime où des armes à feu ont été utilisées
Classifiez et identifiez les résidus de tir (RT) à partir de particules environnementales. Reconstituez les scènes de crime où des armes à feu ont été utilisées. Les résidus de tir (RT) sont des particules provenant de composants ayant partiellement réagi à l'amorce et au propulseur explosifs, provenant de la balle, de la douille et de l'arme à feu.

Les particules de RT uniques présentent une signature chimique spécifique ; plus communément la combinaison de plomb, baryum et antimoine. En outre, les particules de RT provenant de munitions de type sans plomb (Sintox) peuvent être examinées. Les microscopes électroniques à balayage avec spectroscopie à rayons X à dispersion d'énergie permettent d'identifier de très petites quantités de particules de RT et d'analyser ultérieurement la morphologie de surface et de la composition des particules de GDT individuelles avec une grande précision.
