FIELD: analytical chemistry.
SUBSTANCE: invention relates to analytical chemistry, namely to methods for elemental analysis of a substance. The method for analyzing the elemental composition of substances includes the introduction of a substance into a heating source, heating of the substance under study and registration of radiation spectra, while heating the substance is carried out to its atomization temperature, then a non-equilibrium electric discharge plasma with an E/N parameter in the range from 20 to 200 Townsends is formed in the heating zone of the substance and the value of the radiation spectra is recorded.
EFFECT: increase in the detection limit and the ability to analyze substances of different aggregate composition, as well as an expansion of the range of analyzed substances.
