Abstract
Adsorption properties of TG-10 and DG-100 carbon blacks modified with pyrocarbon were studied by gas chromatography in the Henry range. The values of specific surface of these adsorbents differ by an order of m agnitude. The data obtained show the possibility of using these adsorb ents for preconcentration of a wide range of organic substances. The o btained temperature dependences of retention volumes may be used to op timize the processes of preconcentration and thermal desorption of tra ce organic compounds from gaseous media.
