Semi-permeable membrane for solid planar oxygen sensor

摘要

An electrochemical sensor (30,130) characterized in that it comprises: electrochemical means including an electrolyte (58), a cathode contacting the said electrolyte (58), an anode contacting the said electrolyte (58), and a semipermeable membrane (60) separating the said electrochemical means from a sample region, the said semipermeable membrane comprising a first polymerization product of at least one nitrile-containing monomer and at least one conjugated diene monomer.
