About this mock
This test probes advanced competency in the hyphenated and spectroscopic techniques central to modern forensic analysis. Questions span GC-MS, LC-MS/MS, and ICP-MS hyphenated platforms, covering ionisation mechanisms, interface design, scan modes, and matrix effects. Vibrational spectroscopy sections address FTIR and Raman principles, spectral interpretation, and forensic applications to fibres, paints, and drugs. Basic NMR is tested through chemical shift reasoning and coupling pattern recognition. Mass-spectral fragmentation interpretation requires candidates to assign molecular ions, base peaks, and characteristic losses. Technique-selection scenarios demand matching analyte physicochemistry to the optimal platform under real-world constraints. Quality-control coverage includes internal standard selection, calibration curve construction, limit-of-detection versus limit-of-quantitation distinctions, and matrix-matched calibration strategies. All 30 questions operate at analysis level, requiring application of principles to fact patterns rather than simple recall. Internationally recognised instrumentation standards and peer-reviewed forensic science literature underpin each item.
