<p><P>PROBLEM TO BE SOLVED: To provide a method of sending a particulate dispersion in a micro flow channel for sending particulates in the micro flow channel at a high recovery efficiency by stabilizing the flow of the particulate dispersion and preventing floatation and deposition of the particulates in the inner wall and bottom face of the flow channel and also preventing clogging and blocking and to provide an apparatus for the method. <P>SOLUTION: The liquid sending method of a particulate dispersion is for sending a layered current of a particulate dispersion containing particulates having a volume average particle diameter of 1.5-1,000μm dispersed in a medium liquid and having a specific gravity of 1.10-0.99 times as high as that of the medium liquid from an introduction part to a discharge part of a micro flow channel having the introduction part and the discharge part and the micro flow channel is so formed as to position the discharge part above the introduction part in the buoyant direction and the angle of the flow channel from the introduction part to the discharge part is controlled to be 0-45°to the buoyant direction. Alternatively, the angle of the wall face of the flow channel from the introduction part to the discharge part is controlled to be 0-45°to the buoyant direction. The particulate dispersion is introduced into the introduction part and the introduced particulate dispersion is sent to the discharge part. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
