    • An electrochemical cell (20) includes a measuring electrode (12) and a reference electrode (14). The reference electrode (14) includes a flowing liquid junction (22) between a reference fill fluid (24) and a sample (18). The flowing liquid junction (22) is configured to inhibit particles (30) from blocking or obstructing it. In one aspect a particle filter (32) is provided before the flowing liquid junction (22) to prevent particles (30) from the fill fluid (24) from entering the flowing liquid junction (22). In another aspect a particle filter (36) is provided after the flowing liquid junction (22) to prevent particles in the sample (18) from entering the flowing liquid junction (22). In another aspect the flowing liquid junction (22) has a diameter that generally increases from an aperture (130) proximate the fill fluid (24) to an aperture (134) proximate the sample (18). One example of such a configuration is a tapered flowing liquid junction (22).
    • 电化学电池(20)包括测量电极(12)和参考电极(14)。 参考电极(14)包括在参考填充流体(24)和样品(18)之间的流动液体接头(22)。 流动的液体接头(22)被构造成抑制颗粒(30)阻塞或阻塞颗粒(30)。 在一个方面,在流动液体接头(22)之前提供颗粒过滤器(32),以防止来自填充流体(24)的颗粒(30)进入流动液体接合部(22)。 在另一方面,在流动液体接合部分(22)之后提供颗粒过滤器(36),以防止样品(18)中的颗粒进入流动液体接合部(22)。 在另一方面,流动的液体接头(22)具有通常从靠近填充流体(24)的孔(130)到靠近样品(18)的孔(134)增加的直径。 这种构造的一个示例是锥形流动液体接合部(22)。
