Amperometric Gas Sensors with Ionic Liquid Electrolytes

The behavior of amperometric gas sensors using room temperature ionic liquid electrolytes is discussed. Ionic liquid electrolytes were used to prepare amperometric gas sensors in conventional and novel, printed configurations. These sensors were demonstrated for monitoring two toxic gases: ammonia and ozone. For ammonia sensors, the response was compared to a commercial sensor. The issues surrounding sensor performance are discussed. New results are also presented for ozone and nitrogen dioxide monitoring with second generation printed sensors using ionic liquids.
