Forensic Chemistry Course

Lesson 1 • Scope and History of Forensic Chemistry

Traces the evolution of forensic chemistry from early toxicology to modern trace analysis. Provides historical context that motivates current methodologies and standards.

Lesson 2 • Safety and Laboratory Ethics

Addresses chemical hazard management, personal protective equipment, and professional ethics. Establishes safe and ethical conduct as prerequisites for all laboratory work.

Lesson 3 • Legal Framework and Admissibility

Covers evidentiary standards governing scientific testimony and laboratory reports. Connects legal requirements to laboratory documentation practices.

Lesson 1 • Chain of Custody Management

Establishes procedures for tracking evidence from scene to courtroom. Unbroken custody records are essential for evidence admissibility.

Lesson 2 • Evidence Collection Techniques

Covers substrate-specific collection methods for biological, chemical, and trace materials. Proper technique prevents cross-contamination and preserves analytical integrity.

Lesson 3 • Sample Stability and Storage

Examines degradation mechanisms and optimal storage conditions for diverse evidence types. Prevents analyte loss that would compromise downstream chemical analysis.

Lesson 1 • Chromatographic Separation Techniques

Covers gas, liquid, and thin-layer chromatography for separating complex mixtures. Separation is prerequisite to accurate identification and quantification of forensic analytes.

Lesson 2 • Microscopy and Elemental Analysis

Introduces optical and electron microscopy alongside elemental techniques for trace evidence. Morphological and elemental data complement molecular identification methods.

Lesson 3 • Quantitative Analysis and Calibration

Teaches calibration curve construction, internal standards, and method validation. Accurate quantification is critical for toxicological thresholds and regulatory comparisons.

Lesson 4 • Mass Spectrometry Principles

Explains ionisation, mass analysis, and detection for definitive compound identification. Mass spectrometry provides the confirmatory power required in forensic casework.

Lesson 1 • Pharmacokinetics and Toxicokinetics

Explains absorption, distribution, metabolism, and excretion as they affect analyte concentrations. Kinetic understanding is essential for interpreting postmortem and antemortem specimens.

Lesson 2 • Biological Specimen Analysis

Covers collection and preparation of blood, urine, hair, and alternative matrices. Matrix selection determines detection windows and analytical strategy.

Lesson 3 • Drug Classes and Detection Methods

Surveys opioids, stimulants, cannabinoids, sedatives, and novel psychoactive substances. Each class requires tailored extraction and confirmatory analytical approaches.

Lesson 4 • Toxicological Report Interpretation

Develops skills for translating analytical data into cause-of-death and impairment opinions. Integrates pharmacokinetics, matrix data, and scene findings into coherent conclusions.

Lesson 1 • Presumptive Color Testing

Introduces colorimetric reagent tests for rapid field and laboratory screening. Results guide confirmatory testing priorities and scene safety decisions.

Lesson 2 • Clandestine Laboratory Investigation

Examines chemical signatures of illicit synthesis routes and precursor identification. Connects manufacturing evidence to specific drug production methods.

Lesson 3 • Confirmatory Identification Techniques

Applies GC-MS, LC-MS, and NMR for definitive drug identification in casework samples. Confirmatory results meet evidentiary standards required for prosecution.

Lesson 4 • Emerging Synthetic Drugs

Addresses analytical challenges posed by novel synthetic cannabinoids, cathinones, and designer opioids. Rapid structural characterisation methods are emphasised for unknown compounds.

Lesson 1 • Soil and Geological Evidence

Uses mineralogical and chemical profiling to associate soil samples with geographic locations. Soil evidence supports scene linkage and suspect movement reconstruction.

Lesson 2 • Paint and Coating Analysis

Applies layer sequence examination and chemical profiling to automotive and architectural paint. Paint transfers are powerful associative evidence in vehicle collision cases.

Lesson 3 • Fibre Analysis

Covers microscopic and spectroscopic characterisation of natural and synthetic fibres. Fibre comparisons establish potential contact between persons or objects.

Lesson 4 • Glass Fracture and Comparison

Examines fracture pattern analysis and refractive index measurement for glass evidence. Glass fragments link suspects to scenes through physical and chemical matching.

Lesson 1 • Post-Blast Residue Analysis

Applies ion chromatography, LC-MS, and colorimetric tests to post-blast debris. Residue identification links recovered materials to specific explosive formulations.

Lesson 2 • Ignitable Liquid Residue Detection

Covers passive headspace concentration, solvent extraction, and GC-MS analysis of fire debris. Accurate detection distinguishes arson accelerants from background pyrolysis products.

Lesson 3 • Fire Chemistry and Combustion

Explains combustion chemistry, fire behaviour, and the chemical changes that occur during burning. Foundational knowledge enables correct interpretation of post-fire residue data.

Lesson 4 • Explosive Classification and Chemistry

Surveys primary, secondary, and improvised explosive compounds and their chemical properties. Classification guides appropriate analytical method selection and safety protocols.

Lesson 1 • Laboratory Information Management

Covers LIMS operation, case file organisation, and audit trail maintenance. Systematic data management ensures traceability and supports quality assurance reviews.

Lesson 2 • Quality Assurance and Accreditation

Applies proficiency testing, blind trials, and corrective action procedures to maintain laboratory standards. Accreditation compliance protects the validity of all analytical results.

Lesson 3 • Forensic Report Writing

Teaches structured report formats, precise language, and appropriate expression of uncertainty. Clear reports prevent misinterpretation by attorneys, judges, and juries.

Lesson 4 • Case Review and Peer Consultation

Develops skills for technical case review, second-opinion requests, and collaborative problem-solving. Peer consultation improves accuracy and defends against cognitive bias.
