EDS x-ray map showing particles randomly oriented, including the particle showing both
top and side surfaces.
This application note illustrates how scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and x-ray micro-computed tomography (CT) can be used for the analysis of glass particles, in order to link them to the glass covering a smartphone. A simulated traceevidence scenario was produced by subjecting an iPhone 4S to a gunshot, generating glass particles from the iPhone’s front and back covers. These particles were collected and served as an ideal case-study for particle analysis and comparison. Read the application note here.
