本文认为RIGAKU理论基体校正系数在熔融样品中对基体效应校正效果不佳的原因是在计算中没有考虑到烧失量的影响。为此,提出了修正计算方法和计算了新的校正系数;并在建材非金属矿产地质样品XRF分析中应用,提高了分析数据的准确度,获得了满意的结果。
This paper argues that the reason why the RIGAKU theoretical matrix correction coefficient is not effective in correcting the matrix effect in a molten sample is that the effect of loss on ignition is not taken into account in the calculation. Therefore, the correction calculation method and the new correction coefficient are proposed. The application of XRF in the analysis of geological samples of non-metallic mineral building materials has improved the accuracy of the analysis data and obtained satisfactory results.
