I like to document the elements present in my fruit sample. Came to know about this EDX spectroscopy and hope it will serve my purpose. My question is whether a single run itself will give a spectrum with all elements which are present in the sample? And how estimation of each elements is done?
When used with 30kV electrons (within a SEM), EDX (or EDS) will give you information on all elements on the sample with confidence (Z>~5-6) in a single spectrum. The spectrum must have high statistics: major peaks with more than 10kcounts.
The quantification is done by considering the intensity of the peak of each element and some corrections (for fluorescence, absorption, etc). The quantification is usually reasonable directly from the EDS software but care must be taken on light elements (Z
