Tescan SEM Live 3D imaging and reconstruction
Scanning the sample from different angles by dynamic tilting of the beam, provides all Tescan microscopes with an inherent 3D beam technology, enabling them to produce live 3D sample imaging. This Live Stereoscopic imaging, patented by Tescan, can provide crucial data,otherwise very difficult to obtain Read more…
Optimizing FEG-SEM combined with an SDD EDX system for automated GSR analysis
Gunshot residue (GSR) analysis by scanning electron microscopy/energy dispersive x-ray spectrometry (SEM/EDX) is routinely performed in forensic science laboratories. At the end of 2011, a field emission gun (FEG)-SEM was installed at the authors’ laboratory for this type of examination. Following the installation of the FEG-SEM, an extensive process was conducted, in
order to determine the optimal operating parameters of this instrument for GSR analysis. Because the nature of synthetic GSR samples Read more…
