the product principle
principles of x-ray fluorescence technology
after stimulated with x-ray bombardment sample, sample produce x-ray fluorescence, x-ray often the element layer atomic layer k and l up the inner electron atoms, outer electrons fill holes are high-energy, added to the low energy high-energy electrons orbit the excess energy by x ray fluorescence radiation, the radiation of spectral line contains the characteristics of the various elements, like fingerprints, and independent of the chemical valence state of the atom. the intensity of the radiation is proportional to the concentration of the element in the sample.
principle of raman spectroscopy
raman spectroscopy is a nondestructive analytical technique that is based on the interaction of light and materials. raman spectroscopy can provide detailed information on the chemical structure, phase and morphology, crystallinity, and molecular interactions of the sample.
raman is a light scattering technique. when the high-intensity incident light of a laser source is scattered by molecules, most of the scattered light has the same wavelength (color) as the incident laser, and this scattering is called rayleigh scattering. however, there is a very small fraction (about 1/109) of scattered light whose wavelength (color) is different from that of the incident light, and whose wavelength change is determined by the chemical structure of the test sample (the so-called scattered material). this fraction of scattered light is called raman scattering.
