EDXRF (Energy Dispersive X-Ray Fluorescence Spectrometer)

Non-Destructive, Fast, and Precise Elemental Analysis

Rigaku NEX CG EDXRF device

Description

In the Energy Dispersive X-Ray Fluorescence Spectrometer (EDXRF), photons emitted from an X-ray source are directed onto the sample to be chemically analyzed. When these photons interact with the atoms in the sample and have sufficient kinetic energy, they eject an electron from the inner shell of the atom, bringing it from the ground state to a higher energy state. When an electron from an upper shell fills this vacancy, energy is released and the atom returns to its ground state. The emitted energy is characteristic fluorescence radiation. The wavelengths of these characteristic rays are fixed and specific to each element, enabling the chemical analysis of the sample.

The Energy Dispersive X-Ray Fluorescence Spectrometer is a simple, sensitive, rapid, non-destructive, and cost-effective analytical technique used to determine the elemental composition of various materials such as solids, liquids, powders, thin films, and metals.

Using appropriate standard materials, quantitative analysis can be performed from ppm levels up to percentage levels. With the EDXRF spectrometer, semi-quantitative determination of all elements from Sodium (Na-11) to Uranium (U-92) can be carried out.
