3 Method summary

Sample was cast into a certain proportion of flux suitable for melting the sample plate X-ray fluorescence spectrometer measurements. In the selected instrument measurement bar by measuring sample pieces melt film analyte characteristic spectral lines of X-ray fluorescence intensity, based on the calibration curve, and the inter-element interference effect it should be corrected to obtain the content of the analyte.
