Electrode Membrane
   Electrode Membrane       
   Your choices are...         
   Glass       The most familiar type of sensing electrode; tailored to produce an increased affinity for various actions. A glass membrane is routinely used for measuring pH and some ions. Sodium Electrode.  Produces an increased affinity for various cations. 
   Solid State       This sensing membrane is made of a uniform or homogeneous solid substance; a single crystal. Fluoride Electrode. 
   Liquid - Ion Exchange       Membrane is a layer of water-immiscible liquid through which ions can be exchanged. Nitrate & calcium electrode. 
   PTFE/Gas Sensing       Plastic body with a hydrophobic gas permeable membrane; this electrode responds to dissolved gases in solution. The dissolved gas diffuses across the membrane into a small volume of buffer, specific for each electrode. Reaction of the gas with the buffer causes a pH change sensed by an internal glass pH electrode. Because the reference element is built-in, a separate reference electrode is not necessary. Carbon dioxide and ammonia are among the species measured by this type of electrode. 
   ISFET       Ion Selective Field Effect Transistor; this type of electrode contains a transistor coated with a chemically sensitive material to measure pH in solution and moist surfaces. As the potential at the chemically active surface changes with the pH, the current induced through the transistor varies. A temperature diode simultaneously monitors the temperature at the sensing surface. The change in current and temperature are correlated by the pH meter to a temperature compensated pH reading. 
   Plastic       This type of electrode has an ion exchange material contained in a solid plastic membrane. The sensed ion is exchanged across the membrane, creating the potential. 
   Other       Specialized or unlisted membrane style.
