XRF is an inorganic elemental analysis technique used on solids, liquids and powders. In XRF, we use an x-ray source to eject an inner electron from an atomic shell, leaving this in a very unstable state. To become more stable, this outer shell electron will relax, release energy and take the place of that missing electron.

X-ray Generator — The Basics. All XRF spectrometers require a source of X-rays, and these are usually provided by an in situ X-ray generator, or, less frequently, by a radioisotope material. A typical X-ray generator passes an electric current through a filament, which causes electrons to be emitted. These electrons are then accelerated by ...

An XRF spectrometer consists of two primary components; the x-ray output and a detector that is sensitive enough to determine fluorescent x-rays from the incident light. The array then emits X-ray or gamma-ray beams into a sample, exciting the electrons within. The inner atoms get displaced and the atoms that replace these are brought down from ...
