X-ray fluorescence - Wikipedia
网页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.
X-Ray Fluorescence (XRF) - Techniques
网页An X-ray fluorescence (XRF) spectrometer is an x-ray instrument used for routine, relatively non-destructive chemical analyses of rocks, minerals, sediments and fluids. It works on wavelength-dispersive spectroscopic principles that …
What is X-ray Fluorescence (XRF) - Horiba
网页X-ray Fluorescence (XRF) is an analytical technique that uses the interaction of X-rays with a material to determine its elemental composition. XRF is suitable for solids, liquids and powders, and in most circumstances is non-destructive. XRF spectroscopy is an effective method for qualitative and quantitative analysis of material composition.
X-Ray Fluorescence - an overview | ScienceDirect Topics
网页X-ray fluorescence (XRF) is a nondestructive analytical technique that allows qualitative and quantitative characterization of solids, liquids, and powders [295,296]. It uses X-ray excitation to provide inorganic elemental analysis from Na up to Bk.
How Does XRF Work? Understanding X-Ray Fluorescence
网页2020年4月21日 · Energy dispersive X-ray fluorescence identifies metals and elements in an object by detecting their signature XRF emission energies. Here’s a detailed explanation of the process: Essentially, all elements have a fixed number of electrons arranged in atomic orbitals around their nuclei.
