  • Patent number: 11313832
    Abstract: A streaming current measurement flow cell, free from potential piston-to-electrode contact, with a flexible, but close-fitting piston and sleeve set, wherein a housing-defined bushing, as it encircles the piston's active segment near its upper end, does so with a short, cylindrical sidewall, the inside diameter of which, in comparison to the active segment's diameter, creates a narrower—but by only 0.002 inch—capillary-sized flow channel between the bushing and the active segment than exists between it and the sleeve. Even so, physical contact between piston and sleeve—a major wear factor—is completely eliminated; and larger particles known to scratch/gouge dielectric surfaces are kept out of the piston/sleeve flow channel.
