The working electrode either oxidises or reduces the target gas with the counter electrode balancing the generated current. If the working electrode oxidises the gas, then the counter electrode must reduce some other molecule to generate an equivalent current, in the opposite sense. For example, where carbon monoxide will be oxidised on the working electrode, oxygen will be reduced on the counter electrode The reference electrode anchors the working electrode at the correct potential to ensure that it stays in the transport limited current plateau of the current-voltage curve.

The Zero Current Problem
Electrochemical amperometric gas sensors have a background current in addition to the current from oxidation or reduction of the sampled gas. This background current is commonly called the zero current These zero currents can be significant and can frustrate attempts to make measurements at low gas concentrations The offsets will be calibrated in mV because the measured signal was converted to mV through a trans-impedance amplifier.

Simple correction by subtraction (ambient temp)
Programming into your software the zero voltage of both the WE and AE as provided by Alphasense and include separately the electronic and sensor offsets, correcting only the sensor offset for temperature. For B4–type sensors the WE area is 1.16 times the area of the AE, hence it would be expected that the AE currents would have to be adjusted by a factor of 1.16
VWE - 1.16 VAE = 0

Simple correction by subtraction (ambient temp)
The adjustment will not be as simple as that because the structures of the electrodes are by no means planar.

NO2 and O3
Two strongly oxidising, unstable gases at low concentrations. Although both cause oxidative stress in humans and should possibly be
considered together, we must separate them.
NO2: most selective, less stable O3: more stable, RH dependent
