About this mock
This test probes advanced competency in the forensic analysis of explosive incidents. It covers explosive classification schemes, the physical chemistry distinguishing deflagration from detonation, and the instrumental methods used to recover and characterise post-blast residues from complex matrices. Questions draw on the operational principles of ion chromatography, gas chromatography-mass spectrometry, scanning electron microscopy with energy-dispersive X-ray spectroscopy, and ion mobility spectrometry as applied to organic and inorganic explosive residues. Improvised explosive device architecture, component identification, and the forensic significance of blast-scene indicators are also examined. Scenarios are set at the analysis level: candidates apply principles to fact patterns, distinguish closely related techniques, and evaluate evidentiary significance. Examples reference internationally accepted practice across multiple jurisdictions.
