X-ray Analyzers













      Basic principles and techniques:

             ▪ XRF is an acronym for x-ray fluorescence, a process whereby electrons are displaced


                from their atomic orbital positions, releasing a burst of energy that is characteristic of a

                specific element.


             ▪ When X-rays interact with a material, they will be scattered, absorbed or diffracted.


             ▪ The scattered X-rays can lose or change their energy after the interaction.


             ▪ Diffraction is usually caused by crystal lattice and it, therefore, occurs if the material

                involved is of crystalline nature.
