x-ray spectrometry

[′eks ‚rā spek′träm·ə·trē]
(spectroscopy)
A technique for quantitative analysis of the elemental composition of specimens. Irradiation of a sample by high-energy electrons, protons, or photons ionizes some of the atoms, which then emit characteristic x-rays whose wavelength depends on the atomic number of the element and whose intensity is related to the concentration of that element.
