10241 IUPAC Gold Book - foamed polyurethane sorbent 10.1351/goldbook.10241 10241 current 1 Sorbent consisting of spherical, micron-sized, agglomerated particles bound together in a rigid and highly porous structure used for the extraction of semi-volatile organic compounds from air in high-volume samplers. Their main attribute is their favourable aerodynamic properties, which permit sampling at high flow rates. Foamed polyurethane sorbents have a minor use for extracting compounds from water.
