Principle of Fluorescent X-ray Generation

Electron Paths and Principle of X-ray Generation Expressed as a Bohr Model

Electron Paths and Principle of X-ray Generation Expressed as a Bohr Model

When a sample is irradiated with X-rays from an X-ray tube, the atoms in the sample generate unique X-rays that are emitted from the sample. Such X-rays are known as "fluorescent X-rays" and they have a unique wavelength and energy that is characteristic of each element that generates them. Consequently, qualitative analysis can be performed by investigating the wavelengths of the X-rays. As the fluorescent X-ray intensity is a function of the concentration, quantitative analysis is also possible by measuring the amount of X-rays at the wavelength specific to each element.
