    摘要: The invention relates to a process and detector for determining organic and inorganic chemical substances by chemiluminescence with ozone, the selectivity and specificness of the detector being a function of the degree of reactivity of the chemical substances with ozone in distinct temperature ranges. The chemiluminescence reaction takes place in the reaction chamber of the detector, in the absence of oxygen, and with thermal control. The detector comprises the following units: ozone generator, reaction chamber, discharge means for gases issuing from the reaction chamber, an optical system, a photomultiplier, amplifier data transformer and recorder.

    摘要: This invention relates to a process for the preparation of silicious polymeric materials and their use in the separation of fluids in the gaseous phase, wherein the materials are obtained through three basic procedures: (a) polymerization of monomeric substances in the presence of high purity submicroscopic silica particles in which the polymerization of the monomers can be followed by a deactivation reaction with silylating agent; (b) addition of high purity submicroscopic silica particles to monomeric substances, and coupling regents, which will react with surface hydroxyl groups on the silica and a polymer or monomers which are forming a polymer in the reaction medium; (c) through dispersion of the high purity submicroscopic particles in plymeric organic substances. The materials obtained in this invention are solid, usually white, highly porous, of relatively high surface area, thermally stable and have good mechanical strength, and when used as a packing material in a gas chromatographic column provide excellent results with respect to permeability, efficiency, and selectivity.
