Chapter 2 Electrochemical Sensors

An electrochemical sensor consists of the following ma-jor components: A. Gas Permeable Membrane (also called hydrophobic membrane): This is used to cover the sensor’s sens- ing (catalyst) electrode and, in some instances, to control the amount of gas molecules reaching the electrode surface. Such barriers are typically made of thin, low-porosity Teflon membranes. Such sen-sors are called ...
