Apparatus for electrochemical analysis

Claim 1

APPARATUS FOR THE ELECTROCHEMICAL ANALYSIS OF SOLUTIONS, SAID APPARATUS COMPRISING A PAIR OF ELECTRICALLY CONDUCTING MEANS PRESENTING OPPOSED FAACES DISPOSED ALONG SURFACES THAT ARE EQUIDISTANT FROM EACH OTHER THROUGHOUT THEIR AREAS, BIASING MEANS FOR CONSTRAINING SAID ELECTRICALLY CONDUCTING MEANS FOR OPERATIVE MOTION RELATIVELY TOWARD AND AWAY FROM EACH OTHER BETWEEN RELATIVE POSITIONS AT WHICH SAID OPPOSED FACES ARE REMOTE FROM AND CONTIGUOUS WITH EACH OTHER, A SOLUTION-ABSORBENT SHEET OF NON-CONDUCTIVE MATERIAL FOR CARRYING THE SOLUTION TO BE ANALYZED DISPOSED BETWEEN AND DETACHABLY CONTACTING A METALLIC SHEET AND ONE OF SAID FACES, SAID ONE OF SAID FACES BEING CARBON, SAID METALLIC SHEET BEING DISPOSED BETWEEN SAID NON-CONDUCTIVE SHEET AND THE OTHER OF SAID FACES IN DETACHABLE, CONTACTING RELATIONSHIP THEREWITH, SAID FACES EACH BEING GREATER IN EXTENT THAN SAID METALLIC SHEET AND SAID NON-CONDUCTIVE SHEET, SAID METALLIC SHEET BEING GREATER IN EXTENT THAN SAID NON-CONDUCTIVE SHEET, EXTERNAL SOURCE MEANS FOR APPLYING A DIRECT CURRENT BETWEEN SAID ONE OF SAID ELECTRICALLY CONDUCTING MEANS AT A POSITIVE POTENTIAL AND THE OTHER OF SAID ELECTRICALLY CONDUCTING MEANS AT GROUND, MICROMETER MEANS FOR DETERMINING THE DISTANCE BETWEEN SAID FACES TO ALLOW DUPLICATION OF SAID DISTANCE BY ADJUSTING SAID BIASING MEANS, AND MEASURING MEANS FOR INDICATING CURRENT FLOW BETWEEN SAID FACES.
