A method is proposed for making quasi-solid specimens for x-ray Γuorescence analysis by the introduction of a thickening agent (gelatin or agar, starch, water-soluble organosilicon polymer) into a liquid aqueous concentrate obtained by crystallization concentration. An organogel is obtained based on
Measurements of X-ray fluorescence spectra versus grazing incident angles provide information on elemental composition as well as density and thickness of near surface layers. Calculations of fluorescence intensities are presented, which are used for the evaluation of data obtained by total reflecti
