• x-ray fluorescence analysis
• capillary optics
• energy-dispersive detector
• diffraction of primary radiation
• systematic errors

It is shown that the spectra of secondary x-radiation obtained in x-ray fluorescence spectrometers with capillary optics contain peaks that are caused by diffraction of the continuous primary spectrum by the material of the sample and are a source of systematic errors and a cause of false determination of elements in quantitative and qualitative analyses.
