Abstract
An electrochemical ethylene sensor and method for ethylene sensing are disclosed. In one aspect, an electrochemical ethylene sensor includes a working electrode and a counter electrode on an electrically insulating substrate. An ionic liquid layer covers the working electrode and counter electrode. In one method, a voltage is applied to the working electrode which is equal to or lower than the voltage required for the onset of oxidation of the material of the working electrode, for example, in the range spanning 700 mV before the onset of oxidation of the material of the working electrode.
