Particle sorting apparatus, particle sorting method, and program

A particle sorting method, comprising the steps of:

• imparting charges to at least a part of droplets discharged from an orifice from which a fluid stream is generated;
• and
• adjusting a charge amount to be imparted to the droplets according to sizes of particles included in the droplets based on a result of scattered light emitted from the particles by irradiating light onto particles;
• an image pickup device that picks up an image of a state of the droplets;
• and
• a droplet judgment section that judges the state of the droplets from the image picked up by the image pickup device,
• wherein the charge control section adjusts the charge amount when the droplet judgment section judges that an adjustment is necessary;
• wherein the droplet judgment section judges that the adjustment is necessary when a small droplet not including the particles exists around the droplets including the particles;
• wherein the sizes of the particles in the droplets are not uniform.

A non-transitory computer readable storage medium having computer readable instructions stored thereon that, when executed, cause a charge control section of a particle sorting apparatus to execute

• a function of adjusting, according to sizes of particles included in droplets discharged from an orifice from which a fluid stream is generated, a charge amount to be imparted to the droplets based on a result of scattered light emitted from the particles by irradiating light onto particles;
• an image pickup device that picks up an image of a state of the droplets;
• and
• a droplet judgment section that judges the state of the droplets from the image picked up by the image pickup device,
• wherein the charge control section adjusts the charge amount when the droplet judgment section judges that an adjustment is necessary;
• wherein the droplet judgment section judges that the adjustment is necessary when a small droplet not including the particles exists around the droplets including the particles;
• wherein the sizes of the particles in the droplets are not uniform.
