Paper Abstract
The possibilities of increasing the sensitivity of energy dispersive X-ray fluorescence analysis (EDXRF) of solutions with the use of special preconcentrating sensors are described in the article. The sensors are made from polycapillary tubes or plates consisting of hundred thousands micro-channels, each containing a micro-grain of collecting sorbent. The kinetic regularities for preconcentration of micro-components from solutions are considered. Experimental results are given for EDXRF analyses of different solutions containing metals and other elements in trace amounts, and the detection limits of tens and hundreds ppb are demonstrated. The pilot sample of a new analytical instrument <> is shortly described.
