A prototype composite electrode consisting of a metallized membrane "outer" cathode, and a conventional "inner" silver disc cathode, both sharing the same electrolyte, is described. Preliminary results indicate that the metallized membrane will act as an oxygen filter, allowing anaesthetic gases such as nitrous oxide, to pass through to the second (inner) cathode, where they may be reduced. Linear relationships exist for oxygen concentration and metallized membrane current; and for nitrous oxide concentration and the second cathodic current. Extension of this technique to measure both halothane and nitrous oxide on the second cathode, simultaneously with oxygen on the metallized membrane, is discussed.
本文描述了一种由金属化膜“外”阴极和传统“内”银盘阴极组成的复合电极原型，二者共用同一电解质。初步结果表明，金属化膜将起到氧气过滤器的作用，使一氧化二氮等麻醉气体通过，到达第二个（内）阴极并在那里被还原。氧气浓度与金属化膜电流之间存在线性关系；一氧化二氮浓度与第二个阴极电流之间也存在线性关系。本文还讨论了将该技术扩展到在第二个阴极上同时测量氟烷和一氧化二氮，并在金属化膜上同时测量氧气的方法。
