Microscopy of Explosives (1722)
COURSE OUTLINE & SYLLABUS
Course schedule: 8:00 a.m. – 5:00 p.m. Monday – Thursday, and 8:00 a.m. – 12:00 p.m. Friday.
Organic, inorganic, military, commercial and improvised explosives are included. The identification techniques are based on morphology, optical crystallography, microchemical tests and visual thermal methods. Proficiency in polarized light microscopy is assumed and necessary.
Prerequisite: course 1201 or equivalent.
• Köhler illumination
• Crystal morphology: crystal systems, symmetry elements, axes, forms, interfacial angles, axial ratios
• Crystal Optics I: refractive index determinations, indices of crystals in each crystal system
• Crystal Optics II: Birefringence, retardation, Michel-Lévy chart, extinction, anomalous optical properties, interference figures
• Microchemical tests: inorganic ions, organic compounds
• Fusion methods: melting points, identity test, form of crystal-front, optical properties of fusion preparations
• Identification schemes for organic and inorganic high explosives
• Isolation and identification of explosive residues
• Identification of unknowns
