The emergence of synchrotron radiation as a new type of light source has injected new vitality into various disciplines in the field of X-ray applications. Many countries in the world have built synchrotron radiation accelerators and put it into use, making the application of synchrotron radiation an unprecedented development. Synchrotron radiation X Ray fluorescence analysis is one of the important aspects. This paper discusses the limitations of conventional X-ray fluorescence analysis, briefly describes the advantages of synchrotron radiation in fluorescence analysis, and points out the new breakthroughs in X-ray fluorescence analysis for the detection of trace elements and micro-area scanning analysis. The status and status of synchrotron radiation X-ray fluorescence analysis both at home and abroad are briefly introduced, and the future development direction is forecasted.
