  • Vapor sensing instrument for ultra trace chemical detection
    Patent number: 8323576
    Abstract: A detector for detecting vapors emitted from analytes includes a housing, a pump and a sensing assembly. The housing has an inlet, an outlet and an enclosed sensing volume therebetween. The pump communicates with the housing for moving a carrier sequentially through the enclosed sensing volume at a predetermined flow rate. The sensing assembly senses the vapors of the analyte delivered by the carrier as the carrier passes through the housing. The sensing assembly includes a sensing unit constructed of an amplifying fluorescent polymer, a source of excitation, a detector, and a convertor assembly.
    Type: Grant

  • Vapor sensing instrument for ultra trace chemical detection
    Patent number: 6558626
    Abstract: A detector for detecting vapors emitted from energetic compounds includes a housing, a pump and a sensing assembly. The housing has an inlet, an outlet and an enclosed sensing volume there between. The pump communicates with the housing for moving a carrier gas sequentially through the enclosed sensing volume at a predetermined flow rate. The sensing assembly senses the vapors of the energetic compound delivered by the carrier gas as the carrier gas passes through the housing. The sensing assembly includes a sensing unit constructed of an amplifying fluorescent polymer, a source of excitation, a light detector, and a convertor assembly.
