Physics

XRF, like any other technique, is firmly rooted in the physics of the photoelectric effect, in which electrons are ionized and transported.


Fluorescence Physics

XRF is just a small part of fluorescence. Let's start with the big picture, answering quesitons like "why is the sky blue" and "why are plants green?"

Rare Elements

Some elements can surprise - techniques on how to not miss them

Other Types of Scatter

There are other types of scattering which occur in samples - they provide other opportunities to learn
