Abstract: To provide a particle separator and a particle separation method improving particle separation efficiency in a PFF (Pinched Flow Fractionation) technique.SOLUTION: In a particle separator, it is found out that a particle separation-treating amount improves nearly proportionately to the duct width 51 of a narrow part in a y-axis direction by elongating the above duct width 51 when defining a flow direction (longitudinal direction) of the duct as x-axis, a direction vertical to an interface between the sample and sheath liquids as z-axis and a direction orthogonal to x- and z-axes as y axis. Besides, it is found that both treatment amount and separability are improved by restraining length variation of the duct width 51 of the narrow part in a z-axis direction. Further, it is found out that the separability together with the treatment amount improves by making the sample and sheath liquids flow in the narrow part so that a flow ratio of both liquids becomes constant in the narrow part.SELECTED DRAWING: Figure 4
