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. In such a cylindrical column, heat treatment was carried out – the evaporation of a solid sample and the condensation of vapors, and then the evaporation of the condensate into the atomization zone, in which vapors are filtered through the porous medium of the graphite filter into the analytical zone. Due to the separation of matrix components and the reduction of interference, the metrological characteristics of the determination of elements in solid organomineral samples are improved.
