ABSTRACT:
A salt bridge for a flow cell which includes a porous bridge element between fluid flow in the flow cell and in an internal reference fluid flow. The bridge element is surrounded by a body with a bore into which different tubes are located about the porous element. A cylindrical anchoring tube adjacent one end of the body is screw threaded into an aperture in the wall of the flow cell so that self-alignment of the salt bridge in the flow cell is effected. The salt bridge provides a conductivity path between the two flow paths without introducing another potential.
