  • Apparatus and method for generating a plurality of isolated effluents
    Patent number: 7129092
    Abstract: An apparatus and a method for rapidly generating a plurality of isolated effluents have been developed. A specific embodiment involves screening a plurality of solids through simultaneously contacting the members of the plurality with a fluid, simultaneously sampling the resulting fluids, and processing the resulting fluids to, for example, determine changes as compared to the feed fluid or as compared to other resulting fluids.
    Type: Grant
    Filed: June 17, 2004
    Date of Patent: October 31, 2006
    Assignee: UOP LLC

  • Apparatus and method for generating a plurality of isolated effluents
    Patent number: 7070999
    Abstract: An apparatus and a method for rapidly generating and processing a plurality of isolated effluents have been developed. A specific embodiment involves screening a plurality of solids through simultaneously contacting the members of the plurality with a fluid, sequentially sampling the resulting fluids, and processing the resulting fluids to, for example, determine changes as compared to the feed fluid or as compared to other resulting fluids.

  • Method and apparatus for expediting analysis of samples
    Patent number: 6968729
    Abstract: The present invention comprises a method for expediting the analysis of a plurality of samples, preferably using gas chromatography. A specific embodiment comprises a dual isothermal heated zone configuration for use in combinatorial chemistry. This involves partitioning the samples into two isothermal zones, allowing detailed analysis of light components in a lower-temperature zone while heavy components are handled in a higher-temperature zone.
