Discrimination of side‐window glass of Korean autos by laser ablation inductively coupled plasma mass spectrometry

Abstract

Discrimination techniques for side-window glass, although not for side mirrors, using chemical compositions combined with multivariate statistical analyses provide evidence for forensic investigations. Copyright © 2016 John Wiley & Sons, Ltd.

Toward Locard’s Exchange Principle: Recent Developments in Forensic Trace Evidence Analysis

“…Examination of glass from car windows is very important during investigations of automotive accidents. LA-ICPMS showed promise for the analysis of glass from car windows . The technique was especially useful when combined with linear discriminant analysis (LDA).…”

Forensic glass examinations—A review focused on elemental spectrochemical analysis

“…Abundant research and casework reports have described the scientific foundations for the elemental analysis of glass by ICP methods (Almirall & Trejos, 2016; Kammrath et al, 2016; Trejos et al, 2020). Most research focused on the selection of relevant and informative elements, assessment of sources of variation such as spatial inhomogeneities for micro‐sampling volumes, within‐sample and between‐source variations of the elemental profiles, evaluation of the method's analytical performance, discrimination capabilities, uncertainties, and error rates (Dorn et al, 2015; Grainger et al, 2012; Heydon et al, 2018; Lee et al, 2016; Sjåstad et al, 2013; Trejos, Koons, Weis, et al, 2013; Weis et al, 2011).…”

A multi-strategy linear discriminant analysis (LDA) method coupled with laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) for discriminating the geographical origin of nephrite

“…23 In the case of multivariate statistical methods, linear discrimination analysis (LDA) is the most widely used for tracing the origins of various gemstones. [24][25][26][27][28] In addition to gemology, the combination of LA-ICP-MS and LDA can also be used as an effective tool in the eld of provenance study in archaeology, 29 food origin classication in foodstuffs, 30 counterfeit identication in commercial trade, 31 habitat discrimination in speciology, 32 forensic investigation in forensic pathology, 33 and mineral exploration in mineralogy. 34 Despite that the LDA method has proven effective in differentiating a material and identifying its origin, the mechanism of origin determination from different origins has not been studied in great depth and the chemometric methods (especially for LDA) applied to the discriminant model and their application context have not been compared and explored.…”
