Technique, electrochemical oxygen permeation

Chen, C.H., Kruidhof, H., Bouwmeester, H.J.M., and Burggraaf, A.J., Ionic conductivity of perovskile LaCo03 measured by oxygen permeation technique, J. Appl. Electrochem., 1997, T7, 71-75. 

An inexpensive, electrochemical probe, sensitive to oxygen partial pressure is used to measure the oxygen composition in a gas permeate stream following gas separation. Separation of air by a barrier material, poly(ethylene carbonate), is shown as an example of probe operation. Separation and calibration techniques demonstrate probe accuracy and reproducibility.
