Abstract
Elemental trace analysis by electron-excited x-ray spectrometry performed in the scanning electron microscope (SEM) with energy dispersive x-ray spectrometry (EDS) can reach a limit of detection of 0.0005 mass fraction for many elements. Exceptions include elements that occur as materials of construction of the EDS detector, including C, Al, and Si, where unavoidable fluorescence induced during x-ray measurement can substantially raise the limit of detection, often by an order of magnitude or more.Proceedings Title
