Japanese silicate rock standard samples and the S2 Ranger XRF Spectrometer are utilized to create a calibration curve for analyzing major element concentrations of silicate rocks. The calibration curve shows strong positive correlations between intensity and concentrations in most of the major elements of standard samples: Si (0.9583), Ti (0.9971), Al (0.9674), Fe (0.9988), Mn (0.9785), Mg (0.9951), Ca (0.9920), Na (0.9710), K (0.9996), and P (0.9199), suggesting a good calibration curve for measuring major elements of silicate rocks. In order to demonstrate the reliability of standard calibration curves, all of the standard samples were tested. The analysis results display narrow analytical deviations, indicating good stability and reliability of the standard calibration curve and analytical instruments. Furthermore, the JA-2 was tested 10 times to examine counting errors of the instrument and avoid instrumental drift. Most of the standard deviation was less than 0.2 wt%, particularly lower 0.05 wt%, such as TiO2, Fe2O3, MnO, K2O, and P2O5. The calibration curve created by the S2 Ranger XRF Spectrometer is proved to be suitable for analyzing major element concentrations of silicate rocks.
