FLOW TYPE ELECTROLYTIC ANALYSIS CELL

摘要

PROBLEM TO BE SOLVED: To provide a flow type electrolytic analysis cell that can electrolyze almost 100% of an electrolytic solution so as to heighten detecting sensitivity by enlarging the area of the working electrode surface coming in contact with the electrolytic solution. SOLUTION: A solution passage 22 is formed between a solution inlet side pressure plate 15 and a solution outlet side pressure plate 16 having electrical insulating property and chemical resistance, and a positioning auxiliary plate 17 is interposed at an intermediate part of the solution passage 22 to arrange a tubular or disc-like analysis cell 9 in close contact. Carbon fiber 21 formed to be filamentous as a working electrode is closely filled inward of the analysis cell 9, and a lead wire 11 is led out from the outside of the analysis cell 9 to form a flow type electrolytic analysis cell electrically connected to the carbon fiber 21. Glassy carbon electrode material heightened in strength with carbon material or glass as a medium is used as the analysis cell 9.
