摘要： A microparticle sorting apparatus includes a detection unit which detects microparticles flowing through a flow path; an imaging device which images a droplet containing the microparticles which is discharged from an orifice provided on an edge portion of the flow path; a charge unit which applies a charge to the droplets; and a control unit which determines a delay time as from a time that the microparticles are detected by the detection unit to the time at which the sum of intensity of an image region imaged by the imaging device reaches a maximum, making it possible for the charge unit to apply a charge to the microparticles once the delay time has lapsed after the microparticles are detected by the detection unit.
