摘要： A method (300) of measuring impedance of a pH electrode (210) is provided. A test current (I) is applied (320) to the pH electrode (210) for a time duration that is less than 50 percent of a time constant that is associated with electrical characteristics of the pH electrode (210). A voltage response of the pH electrode is measured (330) when the test current (I) is applied to the pH electrode (210). An impedance of the pH electrode is calculated as a function of the voltage response (340).

摘要： 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).
