X-ray fluorescence (XRF) analysis has a wide range of applications because it allows quick and non-destructive qualitative and quantitative analysis of contained elements with simple sample preprocessing and has excellent measurement reproducibility. It is used in the industrial fields of steel, non-ferrous metals, mining, petroleum, ceramics, cement, and for R & D and quality control of electronic materials such as multilayer capacitors and piezoelectric elements.

In the environmental analysis field, XRF analysis is mainly used for hazardous element analysis, and is applied to screening analysis of restricted substances according to the RoHS directive and contaminated soil. XRF analysis is environmentally friendly because it does not produce waste liquid unlike ICP and ICP-MS analysis, both official methods for water analysis. Therefore, the application of XRF analysis to water quality management of industrial wastewater, agricultural water, springs, rivers, lakes is expected to increase.
