介绍了一种由金属化膜外阴极和常规内银盘阴极共用电解液组成的复合电极样机。金属化的膜可以起到O2过滤器的作用，允许像N2O这样的麻醉气体通过第二(内)阴极，在那里它们可以被还原。O2浓度与金属化膜电流、N2O浓度与第二阴极电流存在线性关系。讨论了将这一技术扩展到在第二阴极上同时测量氟烷和N2O，并在金属化膜上同时测量O2。
A prototype composite electrode consisting of a metallized membrane outer cathode and a conventional inner Ag disc cathode, both sharing the same electrolyte, is described. The metallized membrane may act as an O2 filter, allowing anesthetic gases such as N2O, to pass through to the 2nd (inner) cathode, where they may be reduced. Linear relationships exist for O2 concentration and metallized membrane current and for N2O concentration and the 2nd cathodic current. Extension of this technique to measure both halothane and N2O on the 2nd cathode, simultaneously with O2 on the metallized membrane, is discussed.
