Analytical solutions supporting forensic science and criminal investigations

Forensic materials analysis plays a critical role in criminal investigations by enabling the identification, classification, and interpretation of trace evidence. From gunshot residue and particulate debris to surface contamination and transferred materials, forensic evidence often exists at the micro- and nanoscale and requires highly sensitive, reproducible analytical methods.

Thermo Scientific forensic solutions combine scanning electron microscopy (SEM), automated particle analysis, elemental characterization, and surface-sensitive chemical analysis to deliver reliable, unbiased, and defensible results. These technologies support forensic laboratories in routine casework, research, and expert testimony by improving throughput, consistency, and confidence in evidence interpretation.

Key application areas

Gunshot Residue (GSR) analysis

Detect, classify and characterize GSR particles using automated SEM-based workflows with manual elemental confirmation, supporting defensible reporting, fully compliant with ASTM E1588-25.

Trace evidence examination

Analyze microscopic fragments such as glass, paint, mineral grains, fibers embedded with inorganics, and particulate debris to support comparative analysis and event reconstruction.

Particle and debris analysis

Automated detection and classification of particles to reduce subjectivity and support high-throughput forensic workflows.

Surface and residue chemistry

Characterize surface contamination, thin residues, corrosion products and transferred materials and layered coatings using surface-sensitive chemical analysis.

Comparative and corroborative analysis

Combine morphology, elemental composition, and spatial chemical information to strengthen evidential interpretation and improve courtroom defensibility.

Quality assurance and method validation

Ensure analytical consistency and confidence through validated workflows, audit-ready documentation, and standards-compliant procedures for forensic laboratories.
