Electrochemical Sensors: A Powerful Tool in Analytical ...

There are three main types of electrochemical sensors: potentiometric, amperometric and conductometric. For potentiometric sensors, a local equilibrium is established at the sensor interface, where either the electrode or membrane potential is measured, and information about the composition of a sample is obtained from the potential difference between two electrodes. Amperometric sensors ...

Chapter 2 Electrochemical Sensors

The micro fuel cell-type electrochemical sensors do not require an external driving voltage. For example, an elec-trochemical sensor specific to oxygen has an anode, ei- ther Pb or Cd, that supplies electrons for the reduction of oxygen at the cathode. During the oxidation of the an-ode, the electrons are released which then travel via an external circuit to the cathode where oxygen molecules ...

How Do Electrochemical Sensors Work? - Analytical ...

· To put things simply, this sensor type works by means of gas diffusion. Gas finds its way into the outlet of the membrane on top of the sensor housing. Once the gas reaches the working electrode, an electrochemical reaction occurs. This reaction is either an oxidation or a reduction, depending on the type of gas.
