X-ray fluorescence - Wikipedia
X-ray fluorescence (XRF) is the emission of characteristic "secondary" (or fluorescent) X-rays from a material that has been excited by being bombarded with high-energy X-rays or gamma rays.
What is XRF Testing? | XRF Guns, Analysis, & Testing
An XRF gun is a non-destructive tool designed to perform elemental analysis on materials. XRF guns, formally called XRF analyzers or XRF machines, perform measurements by harnessing the power of X-ray fluorescence (XRF), specifically what is called energy dispersive x-ray fluorescence (EDXRF).
What is XRF (X-ray Fluorescence) and How Does it Work?
2020年1月28日 · XRF (X-ray fluorescence) is a non-destructive analytical technique used to determine the elemental composition of materials. XRF analyzers determine the chemistry of a sample by measuring the fluorescent (or secondary) X-ray emitted from a sample when it is excited by a primary X-ray source.

Principle of XRF Analysis : Hitachi High-Tech Corporation
X-ray fluorescence analysis is a method that uses characteristic X-rays (fluorescent X-rays) generated when X-rays irradiate a substance.
How does XRF work? - Bruker
XRF describes the process where some high-energy radiation excites atoms by shooting out electrons from the innermost orbitals. When the atom relaxes, that is, when outer electrons fill inner shells, X-Ray fluorescence radiation is emitted. All this happens without touching or damaging the sample.
X-ray fluorescence (XRF) - Material Testing Expert
XRF (X-ray fluorescence) is a powerful analytical technique that is widely used in various industries to determine the elemental composition of materials. It is a non-destructive method that measures the fluorescent X-rays emitted from a sample when it …
XRF is an analytical method to determine the chemical composition of all kinds of materials. The materials can be in solid, liquid, powder, filtered or other form. XRF can also sometimes be used to determine the thickness and composition of layers and coatings.
X-Ray Fluorescence Spectroscopy (XRF) – Basics
The energy dispersive X-ray fluorescence spectroscopy (XRF) is a method for measuring the thickness of coatings and for analysing materials. It can be used for the qualitative and quantitative determination of the elemental composition of a material sample as well as for measuring coatings and coating systems.
What is XRF testing and do I need it?
2022年2月4日 · XRF stands for X-Ray Fluorescence. This method tests materials by hitting them with X-rays and recording the resulting fluorescent X-rays that are emitted. Each element releases a unique signal and measuring this determines the concentration of the element being tested.
