The objective of the present invention is to purify and concentrate differentiated cells derived from ES cells or iPS cells, for example, without damaging the cells. This problem can be solved by means of a device for analyzing and isolating fine particles, the device including a flow-path cartridge according to the present invention, a light radiating means, a detecting means for detecting fine particles of interest, and a force generating means, wherein there are formed in the cartridge: a sample reservoir coupled to a first flow path; a fourth branched flow path and a fifth branched flow path which are coupled to the first flow path; a number 3A reservoir coupled to the fourth branched flow path; a number 3B reservoir coupled to the fifth branched flow path; and a fourth reservoir which accumulates fine particles that have not been split off; and wherein each reservoir has a means for equalizing the air pressure inside the reservoir and the air pressure in an air-pressure control system in each device, and the flows in the flow paths within the cartridge are controlled by controlling the air pressure in each reservoir using the air-pressure control systems in each device. |
