Abstract
A design is proposed for a crucible electrothermal atomizer with a vertical arrangement of evaporation, condensation, and atomization zones in graphite cylindrical blocks with transverse heating. The heat treatment is carried out in such a cylindrical column: the evaporation of a solid sample evaporation and the condensation of vapors, and then the evaporation of the condensate into the atomization zone, in which vapors were filtered through the porous medium of the graphite filter into the analytical zone. The metrological characteristics of the determination of elements in solid organomineral samples are improved due to the separation of matrix components and the reduction of interference.
