用熔融制样技术的X射线荧光光谱法对硅酸盐样品中10个常见主,次量组分进行全分析,可以消除样品的颗粒度效应和矿物效应。但是元素间的吸收-增强效应仍需进行校正。本文用NBSGSC程序计算硅酸盐试样熔融片体系的理论α系数,仅用10只标样进行校正,在较宽的浓度范围内成功地进行了硅酸盐试样的联机全分析,该法具有通用性强,仅需少量标样以及校正结果准确等优点。 X-ray fluorescence spectrometry of melt sample preparation for total analysis of 10 common primary and secondary components in silicate samples can eliminate the particle size effect and mineral effect of the sample. However, the absorption between elements - enhanced effect still need to be corrected. In this paper, the theoretical α coefficient of silicate sample melt sheet system was calculated by NBSGSC program. Only 10 samples were calibrated, and the full online analysis of silicate samples was successfully carried out in a wide range of concentration. With versatility, only a small amount of standard and the correct calibration results and so on.
