One object of the present invention is to provide a method or apparatus for purifying target particles from high-concentration particles in a short time. The above problem can be solved by a method for purifying target particles, characterized in that the method comprises a step of sorting the target particles from a high concentration of non-target particles, wherein the sorting step is repeated for three times or more.

Method for purifying particles, method for dispensing a single particle, method for analyzing cell cluster, and apparatus using the same

The object of the present invention is to provide a technique for dispensing cells as single cells. The above problem can be solved by an apparatus for dispensing particles comprising a transparent hollow pipette for dispensing sample liquid containing particles, and an image capturing means, wherein the devise has means for capturing two or more images of the dispensing liquid in the hollow pipette; means for comparing two or more shot images, distinguishing a moved particle-like substance from an unmoved particle-like substance in the image-captured particle-like substances, and identifying the moved particle-like substance as a suspended particle; and means for dispensing a sample liquid containing a target number of suspended particles.
