Forensic discrimination of headlight glass by analysis of trace impurities with synchrotron radiation X-ray fluorescence spectrometry and ICP-MS

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.…”

“…[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. This method has another advantage of simple sample preparation and short measurement time.…”

Complementary analysis of trace elements in nail samples using instrumental neutron activation analysis and inductively coupled plasma mass spectrometry

“…Inductively coupled plasma-mass spectrometry has advantages that it doesn't require special facility such as nuclear reactor and has a potential for high sensitivity, multi-elemental analysis. This method has been also widely used for determination of trace elements in glass 15,16) , steel wires 17) or lead shotgun pellets 18) .…”

Nondestructive Analysis of Silver in Gold Foil Using Synchrotron Radiation X-ray Fluorescence Spectrometry

“…6 The technique has been also studied for the examination of physical evidence in the forensic science field. 7,8 One of the advantages of SR-XRF is that valuable forensic samples can be analyzed without destruction. It does not require complicated pretreatment, which is indispensable for analysis using ICP-AES.…”
