Abstract: The accuracy of quantitative energy dispersive X-ray spectrometry on electron scanning microscope was studied for various types of aluminium and copper alloys. Analysis were based on fitted standardless method. Reference materials with known composition were used and average relative error was calculated. The deviations of  results were discussed related to interelement effects of the analysed samples.

Keywords: Energy dispersive spectrometry, accuracy, standardless quantitative microanalysis.
