Title: Double-segment conical electrode
Inventor: SCHAEFER WIELAND PROF DR
IPC: G01N27/30
Filed: 1993-02-05
Abstract: The double-segment conical electrode consists of two truncated cone segments (3, 5) which are electrically insulated from one another and are arranged one on top of the other and are embedded at the top and at the bottom in insulating material (2, 4, 6). The electrode segments can be polarised independently of one another. At the upper segment (3) (working electrode) a solution of higher density is produced as a result of the electrode dissolving, the said solution flowing downwards on the conical surface which increases downwards, and arrives at the lower electrode (5) (indicator electrode), as a result of which an electrochemical characterisation of the product formed in the upper segment is possible. By stacking the electrode segments they are made easy to replace. The double-segment conical electrode is particularly suitable for examining corrosion or for kinetic electrode measurements. <IMAGE>
