Filed:

Aug 27, 2004

Appl. No.:

10/928987

Inventors:

Craig A. Aker - Stillwater OK, US
Colin J. Cumming - Stillwater OK, US
Mark E. Fisher - Stillwater OK, US
Michael J. Fox - Glencoe OK, US
Marcus J. laGrone - Cushing OK, US
Dennis K. Reust - Stillwater OK, US

Assignee:

FLIR Systems, Inc. - Wilsonville OR

International Classification:

G01N 21/64

US Classification:

422 91, 422 8205, 422 8207, 422 8208, 422 8211

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.

Appl. No.:

13/516088

Inventors:

Brian Dwayne O'Dell - Stillwater OK, US
Marcus LaGrone - Oklahoma City OK, US
Martin Leuschen - Madison WI, US

International Classification:

G01N 7/00
G01N 37/00

US Classification:

73 102, 73 3105

Abstract:

The invention provides for a multiple analyte detector that is capable of detecting and identifying explosive, chemical or biological substances having multiple analytes with a single system having multiple reporters. The reporters include fluorescent polymers, conducting polymers, metal oxide elements electrochemical cells, etc. The reporters may be combinations of other reporters that are optimized for broadband detection.

International Classification:

G01N 2164

US Classification:

422 91, 422 8208, 436106, 436172

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.
