I show how an Xray 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 http://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.

Good overall description of XRF: https://phys.libretexts.org/Bookshelv...
