  • Publication number: 20230158497
    Abstract: A system, apparatus, and method include a pump to deliver vapor including airborne contaminants including organic compounds including a target analyte; a collector to transfer the airborne contaminants by autonomous liquid extraction into a mobile organic liquid phase; a micro-fluidic chamber including immobilized biorecognition elements that bind to analytes delivered from the mobile organic liquid phase; a mechanism to introduce the mobile organic liquid phase to a buffer containing a plurality of substrates causing a series of biochemical reactions that create a change corresponding to a concentration of the target analyte; and a detector to perform real-time analysis that correlates to a concentration of the organic compounds to determine a presence of the target analyte.
    Type: Application

  • Publication number: 20070204749
    Abstract: The present invention includes a gas chromatograph column and method of making the same that provide a substantial advance in the art of gas chromatography. The gas chromatograph column includes a first manifold defining a first internal fluid path, a second manifold defining a second internal fluid path and a plurality of tubes. Each of the plurality of tubes defines a fluid path therein, and is mountable with the first manifold and the second manifold such that the first internal fluid path is in fluid communication with the second internal fluid path. Additional features of the present invention include heating and cooling capabilities for ensuring proper fluid flow as welt as the ability to align two or more gas chromatograph columns in series or in parallel for analysis of one or more samples simultaneously.
