Abstract
A system which irradiates light onto a liquid flow containing a biological particle, detects the light therefrom to collect biological information thereon, and sorts the biological particle based upon the biological information, comprises an optical detector for detecting the light from the biological particle; an imaging device for imaging the flow and a droplet split off the flow; means for calculating, based upon the image taken by the imaging device, a distance from a detection point where the optical detector detects the light from the biological particle to a lower end position of the flow, and an interval between adjacent droplets split off the flow, thereby calculating a time that the particle moves from the detection point to the lower end position, based upon the distance and the interval; and means for providing the flow with electrons of a predetermined polarity depending upon the feature of the biological particle, when the calculated time passes after the optical detector detects the light from the biological particle. Thus, the structure of the system for sorting the biological particles can be simplified and the sorting accuracy can be improved.
