Abstract
Disclosed is a solid-liquid separation method including: sucking a suspension containing particles, through an opening formed at a leading end of a suction nozzle, into the suction nozzle; allowing at least a part of the particles contained in the sucked suspension, to sediment to be clogged in the suction nozzle; and ejecting a liquid inside the suction nozzle, through the opening of the suction nozzle clogged with the particles.
Claims18
A solid-liquid separation method comprising:
- sucking a suspension containing particles, through an opening formed at a leading end of a suction nozzle, into the suction nozzle;
- allowing at least a part of the particles contained in the sucked suspension, to sediment by gravity to be clogged in the suction nozzle;
- and
- ejecting a liquid inside the suction nozzle, through the opening of the suction nozzle clogged with the particles, wherein
- a minimum opening diameter of the suction nozzle is greater than a maximum diameter of the particles, and is smaller than six times the maximum diameter of the particles,
- with respect to a particle diameter and a particle diameter distribution, the particles have D90-D10 being not smaller than 120 μm and D50 being not smaller than 170 μm,
- an inner diameter of the suction nozzle is gradually reduced toward the leading end.

A solid-liquid separation apparatus comprising:
- a suction unit to which a suction nozzle having an opening formed at a leading end thereof is attached;
- a controller programmed to control operation of the suction unit;
- and
- a container supporting body configured to support a container storing a sample liquid that contains a target substance, and particles configured to absorb the target substance thereon, wherein
- the controller is programmed to control the suction unit so as to
- suck at least a part of a suspension of the sample liquid containing the particles, through the opening into the suction nozzle,
- allow at least a part of the particles contained in the sucked suspension, to sediment by gravity to be clogged in the suction nozzle, and
- eject a sample liquid inside the suction nozzle, through the opening of the suction nozzle clogged with the particles, thereby causing the particles having the target substance absorbed thereon, to remain in the suction nozzle, wherein
- a minimum opening diameter of the suction nozzle is greater than a maximum diameter of the particles, and is smaller than six times the maximum diameter of the particles,
- with respect to a particle diameter and a particle diameter distribution, the particles have D90-D10 being not smaller than 120 μm and D50 being not smaller than 170 μm,
- an inner diameter of the suction nozzle is gradually reduced toward the leading end.
