Abstract  The microenergy dispersive X-ray fluorescence spectrometry (μ-EDXRF) can provide the information of the micro-area chemical components and the distribution of elements for the materials, which plays an important role in the qualitative and semi-quantitative analysis. It is widely used in geology, archeology and material science. The μ-EDXRF in this paper was used to study the interference peaks in crystal analysis. The methods to identify, reduce and eliminate the interference peaks were summarized. The research methods would be contributed to ensure the accuracy of the results of crystalline μ-EDXRF analysis.

Keywords  μ-EDXRF;qualitative analysis;characteristic X-ray;interference peaks
