Abstract：Over more than 100 years, the development of X-ray spectrometry (XRS) has made great progress. Due to its unique analysis ability in nondestructive testing, in situ and micro-size analysis as well as accurate quantitative analysis of major components, XRS has played important roles in natural exploration, scientific research, technical progress and production application. However, the greatest challenges for XRS are insufficient sensitivity, difficulty in determination of light elements and identification of elemental species. In recent years, with the development of excitation light source, detection means and preparation technology of optical components as well as the in-depth research of elementary particle physics, XRS analysis technique has showed new development trend in some fields, such as reducing detection limit, developing new types of laboratory spectrometers to determine elemental species, and analysis of light elements by muonic X-ray emission spectrometry(μXES). Those studies have become the new trend of discipline development which should be paid attention at present and in near future.
