电子探针定量分析实质上就是将测量的强度比率K值换算成百分浓度C值。也就是说,定量分析主要需要解决两个问题:准确测定强度比率K值和确定可靠的修正计算模型。为了测准K值,除了认真掌握好实验测量技术外,必须要有很好的标样。所谓“标样”是指成分已知、均匀性好和稳定的试样,它可以是纯元素,也可以是化合物。它的质量如何直接影响K值测量的准确度,从而影响定量分析的精度。我们为了开展轻元 Electronic probe quantitative analysis is essentially the measured intensity ratio K value is converted to percentage concentration C value. In other words, the quantitative analysis of the main need to solve two problems: accurate determination of the intensity ratio K value and to determine reliable correction calculation model. In order to test the K value, in addition to carefully grasp the experimental measurement techniques, there must be a good standard sample. The so-called “standard” refers to the known components, good uniformity and stability of the sample, which can be pure elements, it can be a compound. How its quality directly affects the accuracy of K value measurement, thus affecting the accuracy of quantitative analysis. We are in order to carry light yuan
