    • A thin film solid state amperometric detector for nitric oxide is provided based upon a mobile cation electrolyte that selectively transmits nitrosonium cations (NO*) therethrough. The presently most preferred embodiment employs NO-.beta.-alumina as the mobile cation electrolyte. The electrodes of the detector are preferably arranged in a bipotentiostat arrangement. The first and second working electrodes share a common reference electrode and a common counter electrode, which are positioned such that the potentials of the first and second working electrodes can be independently controlled. The first working electrode is exposed to a fluid (liquid or gaseous), whereas the second working electrode is normally isolated from the fluid. The first working electrode is set at a potential capable of oxidizing NO to NO+, the NO+ moves through the mobile cation solid electrolyte to the second electrode, and the second working electrode is set at a potential capable of reducing the NO+ back to NO. The detector has a diffusion barrier for the nitric oxide so that the voltage-current characteristics of the detector under diffusion limiting conditions are proportional to the concentration of nitric oxide in a fluid.
    • 基于通过其选择性地转移亚硝鎓阳离子(NO *)的移动阳离子电解质提供用于一氧化氮的薄膜固态电流计检测器。 目前最优选的实施方案使用NO-β-氧化铝作为可移动阳离子电解质。 检测器的电极优选地布置成双重定位装置。 第一工作电极和第二工作电极共用公共参考电极和公共对电极,其被定位成使得可以独立地控制第一和第二工作电极的电位。 第一工作电极暴露于流体(液体或气体),而第二工作电极通常与流体隔离。 第一工作电极被设定为能够将NO氧化成NO +的电位,NO +通过移动阳离子固体电解质移动到第二电极,并且将第二工作电极设定为能够将NO +还原为NO的电位。 检测器具有用于一氧化氮的扩散阻挡层,使得扩散限制条件下的检测器的电压 - 电流特性与流体中一氧化氮的浓度成比例。
