Microspectrophotometry uses light absorption techniques to analyze microscopic samples often encountered in criminal casework. Its non-destructive analysis capabilities have found numerous applications in forensic laboratories.
Drug & Poison IdentificationMicrospectrometers like the
K5600/K5600C Nano Spectrophotometer allow rapid screening of seized drug evidence at the microgram scale. Absorbance spectra reveal identity by matching reference standards. This enables fast detection of new psychoactive substances.
Toxicological analysis relies on microspectrophotometry to identify xenobiotics in biological samples at trace levels. Spectral library searching aids forensic toxicologists in linking analytical results to causes of death.
Fiber & Paint AnalysesFibers transferred at crime scenes may be examined and sorted. Measurement of fluorescent properties and emission/excitation peaks aid in differentiation and association to known samples.
Characterization of automotive, aerospace, and building paint chips uses spectroscopy to extract layering information and elemental signatures for matching debris to potential sources.
Tool Mark Comparisons
Toolmarks left on surfaces communicate criminal methodologies. Microspectrophotometric analyses of striations, impressions, and wear patterns supply discriminating signatures for developing forensic intelligence leads.
Its combination of non-destructive analysis, sensitivity, specificity, and quantitative absorption measurements position the microspectrophotometer as a powerful multivariate analytical technique for various forensic applications.
