Problems solved by technology

[0004] However, when dispensing samples such as cells in this way, there is a problem that when dispensing, if the sample is a biological cell, the death rate of the sample after dispensing will be high because the small liquid droplets containing the sample To withstand high-frequency vibration and high voltage of several thousand volts, even if the sample survives, it cannot ensure that the sample is in a normal state, especially it will adversely affect the cultivation and differentiation of stem cells
Moreover, when dispensing the sample, it is necessary to form small droplets. In addition to being exposed to ultrasonic waves and electric charges, a large amount of air is also exposed, which may contaminate the liquid droplets containing the sample or damage the sample.
[0005] In addition, there is also the following problem: in the multi-sample dispensing operation performed by the dispensing unit, when selecting a dispensing target well from wells (well), it is necessary to perform mechanical movement work (mechanical movement work), which makes the Score betting is time consuming

Abstract

Provided is a specimen identification and dispensation device and a specimen identification and dispensation method. A specimen identification and dispensation device has an optical measurement device (12) which is an identification part for measuring and identifying optical information on a specimen (S) by emitting exciting light (L) to the specimen (S) being a measurement target dispersed in a liquid flowing through inside of a capillary (21), a dispensation part (13) for dispensing the identified specimen (S) into wells (W) being sections to be dispensed through a nozzle (30), and a concentration adjustment part (400) which adjusts the number of the specimens (S) contained in an aliquot solution to a desired number according to the concentration of a sample liquid and the amount of thealiquot solution. The dispensation part (13) is movable three-dimensionally with respect to the identification part (12) and the nozzle (30).

Description

technical field [0001] The invention relates to a sample identification and dispensing device and a sample identification and dispensing method, in particular to dispensing the sample at a specified sample dispensing position after identifying the sample according to the optical information of the separated sample, A sample identifying and dispensing device and a sample identifying and dispensing method that can shorten the processing time of dispensing operations without causing contamination (pollution) or affecting the sample. Background technique [0002] A method has been proposed in which samples such as cells (fine substances to be measured) are dispersed in a liquid, the liquid flows in a capillary, and the liquid flow is irradiated with light from a light source, thereby measuring the optical information of the sample in the liquid flow ( fluorescence information) for sample identification. After the sample is recognized, it receives ultrasonic vibrations from the ...
