Atomic absorption determination of elements in natural samples using a vaporization crucible with two condensation zones

It is shown that elements can be determined in natural samples and concentrates using a vaporization crucible with two condensation zones. After vaporization in the crucible, element vapors first enter the heated condensation zone, in which some elements are condensed and the residual amounts of organometallic substances decompose, and then they enter the “cold” condensation zone. To analyze the condensates after the fractional evaporation of the sample, an atomizer was proposed with two vaporization zones and a common analytical zone. The performance characteristics of metal determination in suspensions of organic and mineral components, concentrates, natural waters, and bottom sediments were improved.
