Title:

PARTICLE ANALYSIS DEVICE

Document Type and Number:

WIPO Patent Application WO/2021/038977

Kind Code:

A1

Abstract:

This particle analysis device includes: an upper liquid space in which a first liquid is stored; a lower liquid space in which a second liquid is stored; a connection hole that connects the upper liquid space and the lower liquid space; and first to fourth through holes. The first to fourth holes each have an opening section that opens at the top surface of the particle analysis device. The first hole and the second hole extend to the upper liquid space. The third hole and the fourth hole extend to the lower liquid space. A first electrode provides an electrical potential to the first liquid in the upper liquid space, via the first hole; and a second electrode provides an electrical potential to the second liquid in the lower liquid space, via the third hole. The opening section of at least one of the first hole and the second hole has an area larger than any other part of the same hole. The opening section of at least one of the third hole and the fourth hole has an area larger than any other part of the same hole.
