An electrochemical gas sensor includes a housing comprising a gas inlet, an electrolyte within the housing, a working electrode in ionic contact with the electrolyte, a counter electrode in ionic contact with the electrolyte and a secondary electrode in ionic contact with the electrolyte. Reaction of target gas at the secondary electrode is less than reaction of target gas at the working electrode. Electronic circuitry of the gas sensor is configured to measure an output from the working electrode and an output from the at least one secondary electrode. A correction factor is determined for correcting the output from the working electrode on the basis of the working electrode output and the secondary electrode output during an assessment in which the electrochemical sensor is exposed to the target gas for a determined period of time.

Stabilization of sensor signal in electrochemical gas sensors

An electrochemical gas sensor includes an electrolyte including at least one ionic liquid which includes an additive portion including at least one organic additive, at least one organometallic additive or at least one inorganic additive.
