In investigative contexts, the detection and analysis of traces and residues are crucial for establishing the facts and resolving judicial cases. OSE SERVICES conducts on-site sampling and carries out in-depth laboratory analyses, including:
As part of our criminalistics work, we perform targeted investigations to detect the presence of dangerous substances and assess associated risks.
We analyze residues and powders, whether related to explosives, toxic materials, or suspicious substances. These analyses help identify potential sources of danger or contamination, as well as their method of use.
Thanks to our case-specific research, we adapt our investigative methods to the nature of each crime scene or incident, ensuring accurate and legally admissible results.
OSE SERVICES is also recognized for its unique expertise in forensic analysis of artworks. We intervene in cases involving forgery, counterfeiting, or legal disputes related to works of art, using rigorous analytical methods tailored to the authentication of artistic objects.
We use chemical analysis techniques to identify the components of inks, pigments, and varnishes found on artworks or historical documents. This helps confirm or refute their origin, period, and authenticity—or reveal signs of forgery.
In addition to analyzing inks and pigments, we examine canvases, paper, and other supports to trace the manufacturing history of the artwork and detect possible signs of deterioration or later human intervention.
These investigations play a critical role in cases of art fraud or forgery, contributing to the protection of cultural heritage.

As part of our criminalistics expertise, we offer advanced analyses of gunshot residues and projectiles. Our services include:
We detect gunshot residues (GSR) on clothing or objects found at the scene, helping to establish proximity to a firearm discharge.
Our experts conduct in-depth analyses of recovered projectiles and fragments. We identify their origin, thereby contributing to the reconstruction of the events leading up to the incident.
