“…Furthermore, the pXRF was applied to 37 black ceramic prints on automotive glasses from a known source to determine its discrimination capability. From the various discrimination methods including ±2 standard deviation (SD), ±3 SD, and principal component analysis (PCA) [1,4,11,12,14], this research employed ±3 SD for discrimination described by Ernst et al [14]. This study determined the effective and suitable indicators to discriminate different black ceramic prints on automotive glasses and to define an appropriate protocol for discriminating black ceramic prints on automotive glasses.…”

Automotive glasses are important forensic evidence often recovered from crime scenes. Black ceramic prints on automotive glasses contains various elements in high concentrations. A portable X-ray fluorescence spectrometer (pXRF) allows an instant and nondestructive analysis of various elements. In this study, the Bruker Tracer 5 g was used as the pXRF equipment. The NIST SRM612 glass standard was used to determine the limit of detection (LODs) of a pXRF and its optimal conditions. The acceleration voltages of 15, 30, and 50 kV were appropriate for measuring Si K α (1.740 keV)-Ni K α (7.473 keV), Cu K α (8.042 keV)-Pb L α (10.552 keV), and after Bi K α (10.839 keV), respectively. The pXRF was used to compare 37 black ceramic prints on automotive glasses from the known source. The samples were divided into two groups: the Pb type and the Bi type. The samples were compared in pairs. The most appropriate and effective indicators for discriminating between the Pb and Bi type of black ceramic prints on automotive glasses were Zr K α /Pb L α and Cu K α /Cr K α for the Pb type, and Zr K α /Bi L α and Cu K α /Cr α for the Bi type, respectively. The samples were compared with other elements detected by pXRF to further discriminate them. 98.9% of all pairs were successfully discriminated. Results showed that black ceramic prints on automotive glasses are able to be discriminated by pXRF.

A comprehensive evaluation was carried out for elemental characterization of automobile glasses having potential forensic application by Energy Dispersive X‐ray Fluorescence (ED‐XRF) spectrometry and Direct Current Atomic Emission Spectroscopy (DC Arc AES). The methods were optimized and validated using geological certified reference materials and glass standard reference material. Total seventeen elements including five major elements (Si, Na, Ca, Mg and Fe) and twelve minor and trace elements (Al, Ti, V, Cr, Mn, Ni, Cu, Zn, Rb, Mo, Zr and Sr) were found to be present. Though DC Arc AES performed better for minor and trace level determination, however, the precision was evaluated as 15–20 % RSD. On the contrary, ED‐XRF performed better for major elements with 5–10 % RSD. The detection limits for the analytes prone to form refractory oxides on heating were found to be poorer in DC Arc AES compared to ED‐XRF. Statistical analyses were also performed to evaluate the reliability of the data obtained by the optimized methods. As a part of forensic applications, the elemental concentrations of minor and trace elements were utilized for the grouping study of the glass samples by cluster analysis using average linkage method.

Glass is a trace material commonly found at crime scenes that can provide valuable information at early investigative stages and during a trial. The forensic analysis of glass has steadily evolved since the 1970s with numerous technological advances in spectroscopy and spectrometry. This article presents an advanced review of the recent literature concerning the forensic examination of glass evidence and discusses the current state and future opportunities of the discipline. The review focuses on established elemental spectrochemical techniques, including Inductively Coupled Plasma methods (ICP), laser‐ablation, and x‐ray Fluorescence (XRF) methods, and newer applications using Laser Induced Breakdown Spectroscopy (LIBS), Raman Spectroscopy, and accelerator and reactor nuclear techniques. A brief overview of the transfer, persistence, interpretation, and analytical schemes implemented in the field is revised to provide context to the discussion of the capabilities and limitations of the current and emerging technology. This article is categorized under: Forensic Chemistry and Trace Evidence > Trace Evidence
