Popis:	A new method for concentrating of microgram amounts of elements before their spectral determination is described. The method is based on the diantipyrilethanes property to divide the organic solvent into two phases, i. e., during the extraction of elements the three liquid phase system is formed. In one of the phases (the “third phase”) 93–98% of the extractable elements are concentrated. Owing to the small volume the third phase may be dropped onto electrodes avoiding evaporating, ashing of extracts and filling of electrodes before spectral determination. This twice of three times reduces the duration of analysis and increases the accuracy and sensibility of determinations. Based on the three liquid phase system the spectrochemical method of the microgram amounts determination Ga, In and Tl(II1) in Mg, Be, Al, Sc, Y, La, Ce, Zn, Cd, Pb has been developed. The use of such systems in analytical chemistry would be perspective.
