Elemental analysis of vehical glass using neutron activation analysis and X-ray fluorescence analysis
Kameník, Jan ; Fikrle, Marek ; Kučera, Jan
Glass microfragments provide valuable information about certain vehicle crimes. The methodology describes application of X-ray fluorescence analysis (XRF) and neutron activation analysis (NAA) of elemental admixtures in vehicle glass fragments. XRF allows rapid and non-destructive test of the sample and helps in selection of protocols for detailed inspections by additional methods. NAA is time demanding, however, has potential to provide robust results for law enforcement agencies. Both methods are described together with protocols of analysis and their variants. The methodology includes results for 80+ vehicle glass samples.
