Thermal analysis techniques in forensics

Forensic Expertise Area : Explosions & Explosives / Chemical Forensics

SHORT DESCRIPTION

Within the field of Chemical Forensics the main aim of the analysis performed is the identification/comparison of compounds/materials. The physical properties of materials (melting point, phase transitions, decomposition, etc.) generally have less value in these forensic investigations.

However, internationally, some forensic laboratories (e.g. within the field of Explosives), use thermal techniques such as thermographic analysis (TGA), (modulated) differential scanning calorimetry ((M)DSC), Evolved Gas Analysis, micro-calorimetry (TAM), …, and in literature there are examples of these kinds of techniques applied in forensics.

The literature research requested should focus on the link between the properties that are determined in thermal analysis techniques and the (potential) forensic applications, with an emphasis on the application within the field of forensic explosives analysis.
