Applied Science | Demo and teardown of an X-ray fluorescence gun (measures chemical composition) @AppliedScience | Uploaded 4 years ago | Updated 4 hours ago
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 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: phys.libretexts.org/Bookshelves/University_Physics/Book%3A_University_Physics_(OpenStax)/Map%3A_University_Physics_III_-_Optics_and_Modern_Physics_(OpenStax)/08%3A_Atomic_Structure/8.06%3A_Atomic_Spectra_and_X-rays

The two XRF guns in this video were generously donated by one of my viewers. Thank you!
