Document Type and Number:
Japanese Patent JP4779261
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method and a device for simply, speedily and highly accurately separating corpuscles, and to implement a sensor to carry out quantitative and qualitative analysis. SOLUTION: Dielectric migration force is exercised on corpuscles contained in a solution 9 flowing in a solution chamber 8 by applying an AC voltage between a pair of electrodes 4, 5 to gather the corpuscles at a position where flow force is balanced with the dielectric migration force. Since the balanced position differs depending on the kind of corpuscles, they can be separated. In addition, the balanced position can be controlled by changing the frequency of the AC voltage and field strength.
