Title:
METHOD FOR REPLACING LIQUID MEDIUM AND FLOW PATH DEVICE FOR SAID METHOD
Document Type and Number:
WIPO Patent Application WO/2017/221898
Kind Code:
A1
Abstract:
The problem addressed by the present invention is replacing a liquid medium. Provided is a method having: a step that is a step for forming a laminar flow formed from a plurality of laminar flow parts by at least two liquids including a sample liquid and a second liquid medium and wherein the sample liquid is a first liquid medium that includes target particles in a dispersed state and the laminar flow includes a first laminar flow part constituted of at least the sample liquid and a second laminar flow part constituted of the second liquid medium; a step that is a step for moving the target particles from the first laminar flow part to the second laminar flow part by acting an outside force on laminar flow and wherein the target particles have at least one physical characteristic making possible movement in the direction of the second laminar flow part by the action of the outside force; and a step that is a step for recovering a laminar flow fraction that includes the target particles from the second laminar flow part and wherein the recovery of the laminar flow fraction is performed from a laminar flow fraction recovery surface perpendicular to the direction of flow of the laminar flow, and the laminar flow fraction recovery surface and cross-section of the first laminar flow part are separated. Also provided is a flow path device for implementing this method.
