Portable X Ray Fluorescence

Throughout this document the term xfa shall be used to designate portable x ray fluorescence analyzers that contain radioactive sources.

Portable x ray fluorescence.

The phenomenon is widely used for elemental analysis and chemical analysis particularly in the investigation of metals glass ceramics and building materials and for research in geochemistry forensic science archaeology and art objects such as paintings. X ray fluorescence xrf spectrometry is an elemental analysis technique with broad application in science and industry. Portable x ray fluorescence pxrf x ray fluorescence is a technique for chemical compositional measurement in which x rays of a known energy are directed towards a target or sample causing the atoms within the material to emit fluorescent x rays at energies characteristic of its elemental composition. Edxrf is the technology commonly used in portable x ray fluorescence analyzers.

Portable x ray fluorescence also known as pxrf is a portable form of elemental analysis instruments based on x ray fluorescence technology. Xrf is based on the principle that individual atoms when excited by an external energy source emit x ray photons of a characteristic energy or wavelength. Portable x ray fluorescence analyzers may contain one or more radioactive sources that bombard the target with gamma radiation. Edxrf is designed to analyze groups of elements simultaneously in order to rapidly determine those elements present in the sample and their relative concentrations in other words the elemental chemistry of the sample.
