DEVICE FOR ELECTROCHEMICAL MEASUREMENTS Russian patent published in 2004 - IPC

FIELD: electrochemistry.

SUBSTANCE: device has electrode system included in measuring circuit, in which as working electrode a portion of researched sample is used, on which a measuring cell is mounted with comparing electrode placed in it and with auxiliary electrode, filled with electrolyte and having open bottom for providing for contact of electrolyte with singled out portion of surface of researched sample. In side slit of base a block is placed with working electrode with developed surface - researched sample, made, for example, porous, fiber or poured and placed in hollow in block body, placed under open bottom of cell, connected through that hollow by means of curved pipe in block body to intermediate tank filled with electrolyte, placed also in block body and having height of measuring cell, while pipe and hollow for working electrode are separated by perforated disk, above which along hollow perimeter a platinum contact ring is placed of conducting material with output from block body. If necessary by means of peristaltic pump a flow-through of electrolyte is provided for through working electrode.

EFFECT: higher effectiveness.
