Аннотация:It is shown that elements can be determined in natural samples and concentrates using a vapor
ization crucible with two condensation zones. After vaporization in the crucible, element vapors enter the heated condensation zone, in which some elements are condensed and residual amounts of organometallic substances decompose, and then 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.
