| Abstract: | A porous polymer capillary column was prepared by in-situ polymerization of di vinylbenzene (DVB) and vinylpyrrolidone (VPD). The performance and separation mecha nism were investigated. The column efficiency slightIy decreases with increaslng content of VPD in polymeric stationary phase. The influence of water and trace oxygen in carrier gas on the column performance was examined and found that this column can be used directly to an alyze organic cornpounds in water. The column has long durability, if the operation tempera ture is below the decornposition point of polymer and the carrier gas used is without oxygen.The column is useful in separation of C1~C9 hydrocarbons, oxygen-containing additives in gasoline, mixture of apolar and polar compounds. |
