I have been collecting EDS map of a sample and I am interested in roughly knowing the concentration of elements relative to each others. The TruQ tool in aztec reports the composition, but unless normalized, it sums up to values below 100% or higher. Is this normal?
I am only interested in relative abundance as I have an idea about the components in the sample. Thanks
If you have a bulk polished specimen, light elements are not major components, map acquisition time is sufficient, and sum values did not differ from 100% too much, then your software gives reliable result.
Yes, this can happen with simple ZAF. However, I do not know if you are using simple ZAF or a similar general quantification software, or if you are using a well qualified standard. The latter will give a more accurate answer.I know you are seeking a quant “roughly.” But I have seen general ZAF quant percentages be off from a well qualified method by as much as 15 - 20%. I know this seems like a lot, but I have seen this kind of error, even when the EDS system is well aligned, when using the general ZAF standard. Just a fair warning.
