    A.R. Flegal, G.M. Scelfo, in Encyclopedia of Food Sciences and Nutrition (Second Edition), X-ray Fluorescence. A rapidly evolving methodology for measuring lead concentrations in situ is with X-ray fluorescence (XRF). Sufficient incident radiation from an X-ray generator or a radioactive source is provided to excite an inner shell electron, with the resultant emission of a fluorescent X-ray.

The XRF method depends on fundamental principles that are common to several other instrumental methods involving interactions between electron beams and x-rays with samples, including: X-ray spectroscopy (e.g., SEM - EDS), X-ray diffraction (), and wavelength dispersive spectroscopy (microprobe WDS).

The analysis of major and trace elements in geological materials by x-ray. The X-ray fluorescence analysis records the following range of energy or wavelengths: E = – 60 keV λ = – nm Apart from the wave properties, light also has the properties of particles.

This is expressed by the term “photon”. In the following we will be using the term quanta or File Size: KB. To perform a X-ray diffraction experiment, we need an x-ray many cases a laboratory X-ray source such as a rotating anode generator producing a X-ray beam of a characteristic wavelength is used.

Intense, tunable X-ray radiation produced by a Synchrotron provides additional advantages. The primary X-ray beam is monochromated by either crystal monochromators, focusing mirrors, or.

In the first stages of the development of X-ray spectroscopy by means of diffraction in crystals, the radiation from ordinary technical X-ray tubes was registered.
