X-ray Fluorescence Spectrometer (XRF)

1、I nstrument Introducation:

The wavelength dispersion X-ray fluorescence spectrometer (XRF) is ZSX primus, made by Rigaku, Japan, with a set of instruments of electrical power unit, cold circulating water equipment and automatic fusion machine. XRF is widely used for geological element analysis, including rocks, soils, sediments, etc, which is simplicity and convenience of operation. Its analyzable elements range is from Be (4) to U (92). XRF is most common for the analysis of major elements, such as SiO2, Al2O3, CaO, Fe2O3T, K2O, MgO, MnO, Na2O, P2O5, TiO2 and LOI.
