METHOD FOR INTEGRATED RESEARCH scintillation SUBSTANCES factionalism by evaporation in the plasma

摘要

1. A method for integrated-scintillation element-phase studies with fractional material by evaporation in a plasma comprising melting and fractional evaporation of the substance by heating the plasma arc from the top of the cylindrical evaporator deep crater bottom electrode with the bottom on which the test substance is placed so as to be at a distance of 2 mm from the upper open edge of the evaporator and the evaporator is completely vaporized in the combustion process of its side walls, introducing the substance into the plasma vapor, am omizatsiyu and excitation of its atoms in plasma, the creation of conditions for obtaining fractional scintillation analytical spectral signals and registration spectral signals using integrated-scintillation method of recording the spectra at which is performed frame by frame synchronous recording of spectral signals with intermittent synchronous periodic momentary accumulation of spectrum signals, the calculation results of the study , wherein signals carried sorting according to the ratio "SNR" and webbings occurrence signals using each periodic accumulation signal, the determination of a useful analytical signals elemental composition of matter using samples of the comparison and the method of calculating the content of the chemical elements of "relation conditional contents" element without knowledge of the mass of the test substance, characterized in that used as the evaporator substance deep cylindrical DC arc electrode crater with a conical bottom with the top down and vertex angle of less than 90 °, is blown from the bottom up llamas
