FIELD: the invention refers to analytical chemistry.
SUBSTANCE: in the mode after a fractional separation of the matrix the probe with elements settled down on its surface is again introduced in the electrothermal atomizer or in the flaming atomizer or in a burner for inductively constrained plasma for evaporation and registration of an analytical signal.
EFFECT: the mode provides possibility of direct analysis of solid samples with the aid of a probe and reduces limits of detection of defined elements.
