摘要： The present invention relates to a reference electrode for use with a measuring electrode for measuring ion activity in a sample solution, the reference electrode comprising: an electrode chamber for holding electrolyte, an electrode element in said electrode chamber, a tubular wall providing a physical barrier between the electrolyte and the sample solution, characterised in that at least one window is provided in the wall, whereby the window is filled with a non-porous electrochemically conductive polymer to render said window electrically conductive. The present invention provides a reference electrode configured with an electrically conductive window formed in the tubular wall that defines the electrode chamber, and this removes the need for the full body of the electrode to be electrochemically active, which in turn eliminates the formation of a salt gradient and consequential immersion errors. The invention also relates to an electrode assembly comprising a reference electrode, in which the reference electrode is combined with a measuring electrode to form a single-unit electrode assembly. The bonding compatibility between the epoxy vinyl ester non-porous electrochemically conductive polymer filling in the window and the epoxy vinyl ester of the tubular wall provides desirable bonding that is chemically temperature and pressure resistant that avoids problems with leakage through the window causing measurement errors, such as diffusion potential errors.

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).

摘要： A flowing junction reference electrode comprising a liquid junction member matched with a filter. The junction member and the filter are situated between a reference electrolyte solution and a sample solution. An array of nanochannels spans the junction member and provides fluid communication between the electrolyte solution and the sample solution. The filter is configured to allow a greater flux of electrolyte than that associated with the junction member. Preferably, the number of pores is greater than the number of nanochannels. The filter is preferably configured to have pores with an inner diameter that is the same or less than the inner diameter of the nanochannels. In some embodiment, the resistance of the filter is made lower relative to the resistance of the junction member by selecting suitable length, number, and inner diameter size for the pores of the filter relative to the nanochannels of the junction member.
