In addition to gas-chromatographic analysis, a
similar problem arises in the adsorption preconcentration of low-molecular polar, first of all, nucleophilic
organic compounds, which is necessary for the determination of these substances in atmospheric air at a
level of maximum permissible and background concentrations. All of the known adsorbents, including
activated charcoals, and liquid stationary phases do
not ensure sufficiently high concentration factors for
these substances in the analysis of humid air [5, 6]
