  • Gas detection system and method
    Patent number: 5879631
    Abstract: A gas detection system and method selectively detects a gas in the presence of nonselected contaminant gases. The system includes a housing having a collection chamber and a sampling chamber containing a variable resister and a molecular sieve. A molecular sieve is positioned between the chambers for selectively passing a target gas from the collection chamber to the sampling chamber. An organic molecular sieve permits only selected low molecular weight gases, such as ammonia and carbon monoxide to come into contact with the sensor.
