Sample identification sorting apparatus and sample identification sorting method

A sample identification sorting apparatus that identifies a sample dispersed in a liquid, the sample being an object to be measured, and sorts a target sample based on a result of identification, the sample identification sorting apparatus comprising:

• an identifying unit having a sample storage section configured to store a sample dispersed in a liquid, a pressure controlling section that delivers the liquid to a flow channel, a light irradiating section that irradiates light on a sample, an optical information measuring section that measures optical information of the sample, and a determining section that determines whether the sample is a target sample or a non-target sample;
• a sorting unit having a sorting nozzle configured to sort a sorting solution containing a target sample into a collecting container, the sorting nozzle having a flow path in communication with the flow path of the identifying unit, a liquid waste collecting section that is configured to perform collection by suction of one of a liquid waste discharged from a tip of the sorting nozzle and a liquid waste containing a non-target sample or a sample determined as being not possible to be sorted, and a collecting container that is configured to collect a sorting solution containing a target sample;
• a moving unit that moves at least one of the sorting nozzle and the collecting container;
• and
• a control unit that causes at least one of the sorting nozzle and the collecting container to move relative to each other based on the optical information measured in the optical information measuring section,
• the liquid waste collecting section having a suction nozzle that is configured to suck one of a liquid waste containing a non-target sample discharged from the tip of the sorting nozzle and a liquid waste containing a non-target sample or a sample determined as being not possible to be sorted.
