标样法是目前最常用的X射线衍射定量相分析方法。几乎所有的标样法都要求将标样加入到待测样品中去。Leroux提出的外标法,因不需要在待测样中加标样而常被采用。其实,这种外标法的建立,仍然未省去称样、混合和做工作曲线等繁杂手续。它的另一个缺点是要求待测样和标样保持完全相同的实验测量条件。本文提出的一个新的外标法省去了所有标样(内标和外标)法中称重、混合等繁琐手续;只要在相同的实验条件下测得各纯相标样的强度,或根据已知含
Standard sample method is currently the most commonly used quantitative X-ray diffraction phase analysis method. Almost all standard methods require that the standard be added to the sample to be tested. The external standard method proposed by Leroux is adopted because it does not need to add the standard sample in the sample to be tested. In fact, the establishment of this kind of external standard law still does not save the complicated procedures of weighing samples, mixing and doing work curves. Another disadvantage of this is that it requires that the test sample and the standard sample retain the exact same experimental measurement conditions. A new external standard method proposed in this paper eliminates the cumbersome procedures of weighing and mixing in all standards (internal standard and external standard); as long as the strength of each pure standard is measured under the same experimental conditions or According to known containing
