3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Melting method A sample preparation method in which the sample is mixed with a certain proportion of mixed flux and an appropriate amount of release agent, and melted at a certain temperature to form a glass sample. 3.2 Tabletting method The sample is prepared with a boric acid edging substrate, or fixed with a plastic ring, etc., and pressed into a sample in a sample press. 3.3 Standardsample A set of samples with a known composition and content and a certain gradient used to draw the working curve, and the chemical composition and physical properties of the sample to be tested Consistent with other aspects. The composition content of the standard sample can cover the content range of quantitative analysis. [Source. GB/T 30905-2014, 3.4, with modification] 3.4 Driftcorrectionsample The sample used to correct the X-ray intensity drift of the instrument requires that its elemental analysis line has appropriate intensity and can be stable for a long time. [Source. GB/T 30905-2014, 3.3, with modification]

4 Principle

The sample made by the melting method or the tableting method, through the X-ray tube to generate primary X-rays and irradiate the surface of the sample, resulting in the characteristics After the X-ray is split by the crystal, the detector measures the X-ray fluorescence intensity at the 2θ angle corresponding to the selected characteristic wavelength, according to the calibration curve ......
