Std-RSF for each element in analytical sample such as gallium matrix was established using aluminum matrix CRM and applied to the quantification of impurities in Ga metals. Three CRMs were used to prepare the calibration curve, and the slope of calibration curve is RSF. Then, Std-RSF was obtained by converting from RSF based on aluminum matrix to RSF based on gallium matrix. As a result, it was confirmed that RSF was almost constant with the concentration of each element. In addition, the quantitative concentration calculated by the IBR for Fe matrix CRM and the Std-RSF obtained by the Al matrix CRM were compared with the standard concentration of the Fe matrix CRM in order to confirm the error of quantified concentration with the different matrix. It was confirmed that quantification was possible with the relative deviation of under 30%. Finally, a quantitative analysis of the impurity elements in the two gallium metals was carried out using the established Std-RSF. Also, the total concentration for impurities in gallium metals was 7.66 mg kg⁻¹ and 0.08 mg kg⁻¹, respectively, and the detection limits of each element were under 0.004, 0.001, 0.007, 0.003, and 0.006 mg kg⁻¹ for Al, Si, Cu, Zn, and Sn.

使用铝基质 CRM 建立分析样品中每种元素（例如镓基质）的 Std-RSF，并将其应用于 Ga 金属中杂质的定量。用三种 CRM 制备校准曲线，校准曲线的斜率为 RSF。然后，通过将基于铝基体的 RSF 转换为基于镓基体的 RSF 得到 Std-RSF。结果证实，RSF随各元素的浓度几乎恒定。此外，通过IBR计算的Fe基体CRM定量浓度和Al基体CRM得到的Std-RSF与Fe基体CRM的标准浓度进行比较，以确认不同基体定量浓度的误差。确认可以进行定量，相对偏差低于 30%。最后，使用已建立的 Std-RSF 对两种镓金属中的杂质元素进行了定量分析。此外，镓金属中杂质的总浓度为 7.66 mg kg^-1和 0.08 mg kg ^-1，Al、Si、Cu、Zn 和 Sn的每种元素的检测限分别低于 0.004、0.001、0.007、0.003 和 0.006 mg kg ^-1。
