3 Method summary
It is compounded in the order of flux, sample, oxidizer, silica and flux. At step temperature, the ternary mixed oxidant will
The qualitative elements and low-valent elements are oxidized into high-valent elements, and lithium bromide is used as a mold release agent. The sample is melted and cast to a dilution ratio of about
1.44 sample piece. Measure the X-ray fluorescence intensity of the characteristic spectrum of the element to be measured in the sample under the optimal measurement conditions of the instrument, and perform
The interference effect between elements is corrected, and the content of the element to be measured in the sample is obtained from the calibration curve.
4 Reagents or materials
Unless otherwise specified, only use reagents confirmed to be analytically pure and third-grade water that meets the requirements of GB/T 6682 in the analysis.
