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.
How Does XRF Work? Understanding X-Ray Fluorescence
网页2020年4月21日 · Energy dispersive X-ray fluorescence (EDXRF), commonly referred to as XRF, is a fast, nondestructive method to measure the elemental composition of a material. But how does XRF work? Here, we will discuss the science behind XRF and explain how it works in handheld analyzers.
How does handheld XRF work? | Thermo Fisher Scientific - US
网页XRF is a non-destructive analytical technique used to determine the elemental composition of materials. Handheld XRF analyzers work by measuring the fluorescent (or secondary) X-rays emitted from a sample when excited by a primary X-ray source.
X-Ray Fluorescence Spectroscopy (XRF) – Basics
网页The energy dispersive X-ray fluorescence spectroscopy (XRF) is a method for measuring the thickness of coatings and for analysing materials.
How does XRF work? - Bruker
网页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.
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.
X-ray fluorescence (XRF) - Rigaku
网页What is X-ray Fluorescence (XRF)? Measure almost any element in almost any matrix. X-ray fluorescence (XRF) provides one of the simplest, most accurate and most economic analytical methods for the determination of elemental composition of many types of …
