Definition
X-ray fluorescence (XRF) analysis is one of the best analytical techniques to perform nondestructive elemental analysis of solid or liquid samples for major and minor components. A sample is excited by bombarding with X-rays causing ejection of inner electrons with subsequent emission of the characteristic (fluorescence) X-rays of the sample. The energy of the fluorescence X-rays is a characteristic of an element, and their intensities are proportional to the number of excited atoms and thus can be used for qualitative and quantitative analysis of the sample .
Introduction
Since discovery of X-rays by Rontgen in 1895, interaction of X-rays with an atom became a target of eager study in physics research, and X-ray spectroscopy was developed (Bertin 1978). At early stage of X-ray spectroscopy development, Moseley (1913) showed that the chemical composition of a substance can be determined with the aid of X-ray spectroscopy. However,...
