1. A method of extracting microparticles, the method comprising detecting target microparticles for extraction in a main flow path which communicates with a pressure chamber,
generating for each of the detected target microparticles a change in a negative pressure in the pressure chamber communicating with the main flow path to separate and extract each of the detected target microparticles flowing in the main flow path into the pressure chamber,
wherein the generating the change of the negative pressure to extract the detected target microparticles comprises
generating a negative change in pressure by a different amount in accordance with a separation between the detected target microparticles.
