Current measurement electrochemical sensors, sensor systems and detection methods (Amperometric electrochemical sensors, sensor systems and detection methods)

摘要

The present invention is a current measuring electrochemical sensor for measuring the concentration of one or more target gas species in a gas sample or gas stream, the sensor comprising at least one electrochemical cell having first and second surface electrodes, (" SAL ") comprising an electrically conductive material such as, but not limited to, at least one portion of the electrolyte layer located between the surface electrode and the SAL such that the SAL is in direct conductive contact with the electrolyte layer And a current measuring electrochemical sensor which is not in direct contact with the surface electrode. A sensor system and a detection method are also provided.
