Determination of acetone and ethanol vapors using semiconductor sensors

Sensors with gas-sensing layers based on tin dioxide with nanosized catalytic additives of palladium, platinum, antimony, and lanthanum have been used to determine ethanol and acetone vapors in air. The use of nonstationary temperature modes, allowed us to reach record-breaking low detection limits...

More Information
Summary:Sensors with gas-sensing layers based on tin dioxide with nanosized catalytic additives of palladium, platinum, antimony, and lanthanum have been used to determine ethanol and acetone vapors in air. The use of nonstationary temperature modes, allowed us to reach record-breaking low detection limits for acetone (∼0.1 ppm). For the first time ethanol and acetone have been selectively determined with a single sensor.
