I show how an X-ray fluorescence gun works, do a teardown and failure analysis, and discuss a new kind of XRF tech now "available" on eBay.
The XRF data can be transferred from the gun to a PC, and analyzed with pymca.sourceforge.net/ I did this for several materials, but ran out of time in this video to show the software usage, which is quite involved.
