摘要： The invention relates to analytical chemistry, in particular, to the spectral absorption analysis with a differential method of measuring concentrations of mercury and benzene vapors. The invention is aimed at creation of an absorption analyzer, which allows to determine the content of mercury and benzene in the carrier gas, with improved analytical performance for benzene. The aim is achieved with an absorption analyzer, which comprises optically coupled components: a photodetector, an analytical cell, a modulator of radiation polarization and a spectral lamp containing a discharge cavity located between magnet poles and connected with means of electric discharge excitation, buffer gas and mercury placed into the spectral lamp, as well as a gas system connecting a sampling port of the analyzer with an input port of the analytical cell by gas communications, wherein the gas system comprises at least three gas channels connecting the sampling port of the analyzer to the input port of the analytical cell via a gas channels selector, while at least one of these gas channels comprises means for removing the benzene from the gas stream, at least one comprises means for removing mercury from the gas stream, at least one is permeable for mercury, at least one is permeable for benzene and at least one has different permeability rates for mercury and benzene.
