MICRO-OBJECT CONCENTRATION DEVICE AND MICRO-OBJECT QUANTITY MEASUREMENT DEVICE AND MICRO-OBJECT CONCENTRATION METHOD AND MICRO-OBJECT QUANTITY MEASUREMENT METHOD

摘要

PROBLEM TO BE SOLVED: To confirm the cleaning state of an electrode in a micro-object concentration device for condensing sample solution containing a micro-object by applying an AC voltage to the electrode regardless of the conductivity or liquid temperature of the sample solution.;SOLUTION: The micro-object concentration device includes: a cell 4 having a first electrode pair 5 and a second electrode pair 6; supply means for supplying cells to sample solution; collection means for collecting the solution from the cells; an AC power source 7 for applying a first AC voltage to the first electrode pair; measurement means 8 for measuring a conductance G1 between the first electrode pair and a conductance G2 between the second electrode pair; and comparison means 9 for comparing the conductance G1 with the conductance G2.;COPYRIGHT: (C)2012,JPO&INPIT
