ABSTRACT:
A sealing ring assembly and an improved method for mounting a sealing ring into an electrochemical cell used for Electrochemical Capacitance Voltage (ECV) profiling measurements. The ring is located in a holder having at least one secondary bore providing fluid communication between a forward face of the holder and the central bore of the ring, directed parallel to but tangentially offset relative to the inner wall of the central bore so as to impart a degree of rotational flow to electrolyte entering the sealing ring through the or each secondary bore which effectively removes gas bubbles and refreshes the electrolyte. The holder facilitates ring removal with a much reduced risk of damage to the delicate sealing surface.
