<strong>High</strong>-energy X-ray<br />
fluorescence<br />
Example: Hg K-edge<br />
Binding <strong>Energy</strong> (keV) at K edge<br />
36.0<br />
•Low Hg<br />
concentration (a<br />
few mg)<br />
•Many commonly used elements, including RE elements •Non-destructive<br />
•Excitation beyond the energy <strong>of</strong> in-house XRF •Hg vapor pressure<br />
•Greater fluorescence yield at K-edge<br />
vs. temperature<br />
•<strong>Use</strong>ful <strong>for</strong> non-destructive detection<br />
