  • Sample preparation for parallel chromatography
    Patent number: 7074327
    Abstract: Systems and methods are provided for preparing samples for chromatographic separations and then chromatographically separating the prepared samples, preferably in a high-throughput fashion utilizing multiple parallel first (fluid) processing regions in fluid communication with multiple parallel second (fluid) processing regions wherein the each second processing region includes a chromatography column. One or more common fluid supplies may be utilized in each of the sample preparation and separation steps to minimize the number of requisite fluid connections and external components such as pumps, reservoirs, pulse dampers, flow controllers, and the like.
    Type: Grant
    Filed: May 7, 2004
    Date of Patent: July 11, 2006
    Assignee: Nanostream, Inc.
    Inventors: Stephen D. O'Connor, Eugene Dantsker, Christoph D. Karp, Mike S. Lee, Surekha Vajjhala
