US Patent:

42569850, Mar 17, 1981

Filed:

Jun 7, 1978

Appl. No.:

5/913280

Inventors:

Louis H. Goodson - Kansas City MO
William B. Jacobs - Overland Park KS

Assignee:

Midwest Research Institute - Kansas City MO

International Classification:

G01N 2712

US Classification:

307308

Abstract:

A gas sensor unit designed to indicate the presence of hydrocarbon vapors but be insensitive to carbon monoxide. The unit comprises two TGS sensors, one covered by a semi-permeable membrane and the other uncovered; the uncovered sensor responds to both crude oil and carbon monoxide, the covered sensor responds only to carbon monoxide. In one embodiment, the two sensors are connected in series; the total response of both sensors and the difference in response between the two sensors are measured, and changes in the parameters indicate the presence of an oil spill. In another embodiment, each sensor's output is compared with its reference voltage; if the uncovered sensor has an output that is higher than its reference while the covered one does not, the presence of an oil spill is indicated.

Abstract:

Air that is desired to be examined for impurities is drawn through a concentrator comprising a cylindrical receptacle into which the air is introduced at the base portion of the receptacle in a direction tangentially of the cylindrical wall. A scrubbing liquid such as water is supplied to the receptacle and withdrawn therefrom on a continuous basis. The quantity of water only partially fills the region at the base of the receptacle where the air is tangentially introduced, with the result that the water is caused to rotate vigorously within the cylindrical wall as a thin film. The air is initially beneath the rotating film but then passes upwardly through it and is efficiently scrubbed. Gaseous and particulate impurities in the air are thus extracted into the water, and the same is drained from the receptacle and monitored for contaminant content.
