  • Apparatus for the continuous production of a standard ionic solution
    Patent number: 5041202
    Abstract: This apparatus essentially comprises a coulometric cell (10) having an electrically insulating tight enclosure (12, 14, 30) containing a cathode (20) and an anode (22) which face one another and defining between them a space (21) for the passage of the solution to be enriched by said ions, a pipe (42) for supplying the solution to be enriched with ions and a pipe (44) for the discharge of the ion-enriched solution and issuing into said space (21), electric supply conductors (24, 26) for the cathode and the anode, the cathode and/or the anode containing said ions and being able to release them during the passage of the current and a current-stabilized electric supply source (28) connected to said conductors (24, 26).
