Electrochemical Ethylene Sensor and Method for Monitoring Ethylene

摘要

This application relates to methods and apparatus for ethylene sensing. An electrochemical ethylene sensor is described with comprises a working electrode (20) and a counter electrode (40) on an electrically insulating substrate (10). An ionic liquid layer (60) covers the working electrode and counter electrode. In use a voltage is be 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 700mV before the onset of oxidation of the material of the working electrode.
