Abstract
An ion exchange membrane for use in sensors which measure dissolved gases. Disclosed is a method for using ion exchangers in gas permeable membranes to maintain optimal conditions in the electrolyte contained within the sensor. This can greatly extend the lifetime and improve the stability relative to sensors of similar size and electrolyte volume that have been constructed using prior art.
