EDX – Energy-dispersive X-ray spectroscopy

Energy-dispersive X-ray spectroscopy, commonly EDX, EDS, or EDXA, refers to the analytical technique used in conjunction with a scanning electron microscope (SEM) in order to identify composition and provide chemical characterization of a specimen. An electron beam is focused onto the sample that collides with and possibly ejects some of the sample’s electrons, forcing [...]

Particle Size Analyzer – Automated SEM EDS

The automotive industry uses particle size distribution analysis in order to control contamination both before and during the assembly process. Information about particle type, size distribution, and morphology is used to identify potential contaminates, as well as minimize the cause of contamination. In order to combat contamination, identifying and sizing particles is the [...]

Forensic Trace Evidence Analysis – Microscopic CSI

Trace evidence encompasses the multitude of materials left at or taken from a crime scene, such as blood droplets, clothing fragments, or gunshot residue. In order for these substances to be useful, they must carefully be preserved and collected at the crime scene, minimizing and controlling the further contact with them as not to [...]

GSR Trace Evidence System Using SEM

Gun Shot Residue (GSR) consists of particles from the explosive primer, both burnt and unburnt, as well as the propellant, bullet fragments, the casing and the firearm used. When the gun is fired, the pressure from the bullet leaving the muzzle forces the debris out of the barrel at a high velocity, and scatters [...]
