A method is proposed for making quasi-solid specimens for x-ray Ñuorescence 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

✦ Synopsis
A program for chemical analysis by energy-dispersive x-ray spectrometry is described. Fluorescent multiplets are Ðtted to a high degree of accuracy by a method using an empirical energy-dependent peak-shape function derived from the spectrometer response to well resolved standard sample spectra. Elemental identiÐcation is accomplished via an interactive peak search and a complete K and L x-ray line library. Matrix correction routines for element quantiÐcation are provided for inÐnitely thick samples with fundamental parameters, including Compton correction, for thin samples and total reÑection (TXRF) geometry and for semi-transparent light matrix pellets (emission-transmission method).
