"Molded" porous polymer monoliths: A novel format for capillary gas chromatography stationary phases

Highly permeable monolithic columns have been prepared directly within capi llaries of various internal diameters by the in situ polymerization of high purity divinylbenzene, characterized, and used as novel stationary phases for gas-solid chromatography. The chromatographic properties of these colum ns are demonstrated ent separation of mixtures of volatile organic as well as their aqueous solutions.
