X-Ray Absorption Spectroscopy (XAS) Technology

The intensity of X-ray will attenuate after passing through the sample, and the degree of attenuation is closely related to the structure and composition of the sample. This technology for studying the relationship between transmission intensity and incident X-ray intensity is called X-ray absorption spectroscopy (XAS) technology. This technology does not rely on the long-range ordered structure, can be used for the study of amorphous materials and has the advantages of small interference and no damage to the sample, which is usually used for qualitative and quantitative analysis of elements in solid (crystal or amorphous), liquid, gas and other samples.
