Forensic Discrimination of Sheet Glass by a Refractive-Index Measurement and Elemental Analysis with Synchrotron Radiation X-ray Fluorescence Spectrometry

Forensic Discrimination of Sheet Glass Exposed to High Temperature by the Determination of Trace Impurities Using ICP-MS

“…A number of studies have reported that comparisons of elemental compositions are useful for the forensic discrimination of glass fragments, 5,6,8,9,12,[15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] and it is not pointed out again in this paper. What should be emphasized here is that a good correlation was observed in the elemental profiles between the non-heated and heated fragments in any of the 5 glasses.…”

“…9,18,19,21,26,[32][33][34][35][36] For this purpose, the mass spectrum of each sheet glass sample was measured in the atomic mass range from m/z = 50 to m/z = 210 while the sample solution was introduced into ICP-MS. The spectra of samples 4 and 5 are shown in Fig.…”

“…If tiny glass fragments found on the clothes of a suspect can be proved to originate from the broken window glass, they can be valuable physical evidence to associate the suspect with the crime. [1][2][3][4][5][6] The forensic glass comparison mentioned above has been conducted by measuring the refractive index (RI) [5][6][7][8][9][10][11][12][13][14] and conducting an analysis of the elemental compositions using procedures such as X-ray fluorescence spectrometry (XRF), 6,8,12,[15][16][17][18][19][20][21][22] inductively coupled plasma atomic emission spectrometry (ICP-AES) 8,15,[23][24][25] and mass spectrometry (ICP-MS). 5,6,9,12,18,[26][27][28][29] An RI measurement can be applied to a glass fragment smaller than 0.1 mm in a maximum width without its destruction.…”

“…(1,61) Synchrotron radiation has been increasingly applied for the detection of trace elements to differentiate glass fragments. (58,59,62) amounts of heavy elements present in different samples; e.g. three different glass samples with matching RI values could be differentiated according to their Ce peak-area ratios, which were found to be 11.6 ± 0.3, 40.1 ± 0.1, and 524.9 ± 0.9.…”

Forensic Identification of Automobile Window Glass Manufacturers in Japan Based on the Refractive Index, X-ray Fluorescence, and X-ray Absorption Fine Structure

“…In general, the forensic analysis of glass is performed using elemental analysis and the refractive index (RI). A variety of methods for elemental analysis, such as X-ray fluorescence spectrometry (XRF), [1][2][3][4] inductively coupled plasma atomic emission spectrometry (ICP-AES), 3 inductively coupled plasma mass spectrometry (ICP-MS), 5,6 and synchrotron XRF 7 have been reported. On the other hand, an oil immersion method for RI has been reported.…”
