Abstract
When determining element concentrations in geological samples by X-ray fluorescence spectrometry using emitters obtained by pressing tablets from powder samples, we revealed the effect of a significant difference in line intensities of characteristic long-wavelength emission (ΔIi) from opposite sides of the emitter. The effects of compacting pressure, mass of emitter, and its surface area on ΔIi were investigated. It was shown that the account of this effect can reduce the error of sample preparation in using compacting pressures lower than 20 t.
