How to calculate the atomic percentage based on the EDS diagram

Dale Henderson  Follow
EDS is a qualitative analysis, which can only show whether there is such an element in the sample.Do not use this to determine the element percentage.

SEM can generally only be qualitative or semi -quantitative. The spectral maps can be directly seen at the atomic percentage. Generally, when you are reviewed, I will let the author provide more information to prove its point of view. If this dataMore critical.

EDX is a quantitative analysis. The sample must steam the carbon -plated electrical membrane. One is to prevent poor electronics, scattering less radiation on the incident electrons, and improve the X -ray intensity generated by the sample.The other is to treat less X -ray absorption of analytic elements and improve the accuracy of quantitative.In the end, C only CK-会 will not produce Yuanfeng interference.If gold is plated, AUM overlaps with MOL, NB-L, SK lines, and the element is misjudgment.
The quantitative correction method includes ZAF, B-A, u0026#216; (ρZ) correction method, XPP correction method.All these quantities are only for elements with more atomic order than 11. So far, there is no quantitative analysis method based on EDX -based light elements.If you have elements of less than 11 in your system, such as you are a polymer system, it is difficult for EDX to give a convincing quantitative result.Therefore, it is recommended that the landlord still uses ICP-MS and other methods.Generally speaking, the peaks of K -series and L systems that may contain a certain atom at the same time. When calculating, you can see which error produced by that line with other elements is less.
