Development and Evaluation of a Standard Method for the Quantitative Determination of Elements in Float Glass Samples by LA-ICP-MS

Abstract

Forensic analysis of glass samples was performed in different laboratories within the NITE-CRIME (Natural Isotopes and Trace Elements in Criminalistics and Environmental Forensics) European Network, using a variety of Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) systems. The main objective of the interlaboratory tests was to cross-validate the different combinations of laser ablation systems with different ICP-MS instruments. A first study using widely available samples, such as the NIST SRM 610 and NIST SRM 612 reference glasses, led to deviations in the determined concentrations for trace elements amongst the laboratories up to 60%. Extensive discussion among the laboratories and the production of new glass reference standards (FGS 1 and FGS 2) established an improved analytical protocol, which was tested on a well-characterized float glass sample (FG 10-1 from the BKA Wiesbaden collection). Subsequently, interlaboratory tests produced improved results for nearly all elements with a deviation o

Forensic Discrimination of Tiny Glass Fragments with Non-flat Surface by Trace Elemental Analysis Using LA-ICP-MS

“…Theˆnal 50 s of the ablation was used for data acquisition. 29 Si was employed as an internal standard during the calibration of data by LA ICP MS to correct for diŠerent ablation yields and instrumental drifts 22) . Elemental concentrations determined by LA ICP MS (Table 4) were su‹ciently close to those obtained by SN ICP MS.…”

“…The reason for relatively large variation of lead concentration in sample 3, 4 and 5 cannot be well understood. It could be partially explained by the use of the ICP MS equipments for other application to samples of high lead matrix, such as lead shotgun pellets 22) .…”

“…Determination of these elements was performed at m/z for isotopes of maximum isotopic abundances and with no interference by the overlapping of isobars of other elements. These 10 elements except Co and Mo were also employed for the discrimination of glass fragments in the previous studies using LA ICP MS 21,22) . Although a Sn peak was observed in the mass spectra of samples 2 and 3, Sn was not included in the analyte elements.…”

Inductively coupled plasma- and glow discharge plasma-sector field mass spectrometry : Part II. Applications

“…129,130 Multi-element analysis of materials and objects in the context of forensic studies or provenance determination has been described in literature as well. [131][132][133][134] The use of LA-ICP-SFMS for the forensic study of glass was exploited comprehensively by Latkoczy et al 135 Determination of Fe in glass for forensic purposes by LA ICP-SFMS was performed by Castro et al 136 Polyatomic interferences due to polyatomic ions, such as 40 Ca 16 57 Fe + are resolved at a mass resolution of 4000. The advantage of the high resolution instrumentation includes its capabilities to achieve lower method detection limits and its capability to conduct multi-elemental analysis during laser ablation.…”

Wavelength Dependence on the Forensic Analysis of Glass by Laser Induced Breakdown Spectroscopy

“…These techniques include spark source mass spectrometry [1], atomic emission spectroscopy [2,4], atomic absorption spectroscopy (AAS) [3], x-ray fluorescence (XRF) [3,4], neutron activation analysis (NAA) [5], scanning electron microscopy (SEM) coupled to both energy dispersive spectroscopy (EDS) and wavelength dispersive spectroscopy [6], particle induced x-ray emission (PIXE) [6], inductively coupled plasma atomic emission spectrometry (ICP-AES) [3,4,7], inductively coupled plasma mass spectrometry (ICP-MS) [8], and laser ablation-ICP-MS (LA-ICP-MS) [9].…”
