PURPOSE:To obtain a cell which is free from liquid leakage and has low noise, high sensitivity and excellent electrolytic efficiency by using a tube electrode formed by inserting a wire-shaped inside electrode into a tube consisting of an ion exchange membrane and winding an outside electrode on the outside surface of the tube. CONSTITUTION:The wire-shaped inside electrode 13 is inserted into the tube 12 consisting of the ion exchange membrane and the outside electrode 14 is wound on the outside circumference of the tube 12 to form the tube electrode. The tube electrode is freely attachably and detachably attached at both ends to a cap part 18 provided with fluid connecting ports 19, 20 on the outside surface and is dipped into an inside liquid 16 of a case 15. Fluid to be measured or fluid for forming a reagent is introduced into the tube electrode through fluid connecting ports 19, 20 and the polarographic measurement is executed in accordance with the current flowing between the electrodes or the reagent is generated by passing the specified current between the electrodes. |
