MICROORGANISM QUANTITY MEASUREMENT CELL AND MICROORGANISM QUANTITY MEASUREMENT DEVICE COMPRISING SAME

摘要

A measurement cell (1) comprises: a measurement chamber (6); an inflow aperture (7) by which a sample solution flows into the measurement chamber (6); an outflow aperture (8) by which the sample solution flows out from the measurement chamber (6); a measurement electrode (12) which is disposed in a location toward the outflow aperture (8) within the measurement chamber (6), captures bacteria which is included in the sample solution which flows in the measurement chamber (6) and whereupon a measurement AC voltage is applied to measure the quantity of the bacteria; a concentration electrode (21a) which is disposed in a location toward the inflow aperture (7) in the measurement chamber (6), and whereupon a concentration AC voltage is applied for imparting a repulsive force which guides the bacteria included in the sample solution to the measurement electrode (12) side; and insulating bodies (20a, 20b) which are disposed upon the concentration electrode (21a), and whereupon an electrical field convergence unit (22) is formed which causes the repulsive force to be generated in a portion of the insulating bodies when the concentration AC voltage is applied to the concentration electrode (21a).
