Resumo

A new modification of the analyzer of mercury vapors in atmospheric air is described. A low pressure mercury capillary lamp filled with natural isotope composition mercury is used as a source of radiation. The transverse Zeeman effect is used for the analysis. Results of the laboratory tests of the analyzer in different gaseous media are presented. Full compensation of nonselective absorption signals is attained. The analyzer sensitivity is estimated to be ±30 ng/m³.
