Quantitative analysis using X-ray diffraction (XRD) (internal standard method)
This is a recommended method for determining the content of specific minerals in a sample (wt%).
This is a quantitative analysis method that utilizes the fact that the intensity of the diffraction lines obtained from X-ray diffraction analysis depends on the mineral content. By creating a calibration curve from samples with known content and adding an internal standard material, it is possible to quantify without considering the influence of the mass absorption coefficient (a coefficient that represents the degree to which the sample itself absorbs X-rays). However, quantitative analysis cannot be performed on samples where the diffraction lines overlap with those of coexisting minerals or where it is difficult to obtain pure standard materials for creating the calibration curve.
