(1) X <strong>Ray</strong> Fluorescence Spectroscopy<br />
“bulk technique”<br />
sample prep = grind sample to powder, make pressed pellet<br />
Method:<br />
• irradiate sample with high energy X-rays<br />
• some electrons knock out inner shell electrons; outer shell electrons fall <strong>and</strong><br />
emit characteristic wavelength secondary X-rays<br />
• intensity of characteristic spectrum relates to quantity; samples with many<br />
elements will result in many spectral line emissions
