Elemental Analysis using EDAX

<<< Draft >>>

EDAX stands for Energy-dispersive X-ray spectroscopy and is used for elemental analysis. A high energy beam of electron is allowed to fall on sample (usually inside electron microscopes such as SEM). The interaction of incident electrons and the atoms results in generation of characteristics X-ray depending upon the energy level of electrons in the sample atoms. These X-ray is then analyzed to detect the elemental content of sample under study.

In my DualBeam focus ion beam system, I have an EDAX system installed. It looks like this



For EDAX special high purity carbon tape is used to mount specimen in stub. These can be bought from here (part number - 16084-4)
