Claims

[Scope of utility model registration request]

(1) A mechanism that sends the sample and sheath liquid to the jet nozzle; A jet nozzle that forms a sheath flow centered on the sample; An irradiation optical system that irradiates the jet stream from the jet nozzle with light; Particles that are irradiated A condensing system that collects the light emitted by receiving the light; An electric system that electrically processes the large signal from the condensing system; and an electric system that applies periodic micro-vibrations to the jet stream from the jet nozzle to generate the jet stream. A particle analysis/preparation device comprising: a separation mechanism that separates the droplets into uniform droplets, applies an electric charge to the droplets containing the necessary particles, and distributes the particles using a strong electrostatic field; 1. A microparticle analysis and separation device characterized by being equipped with a means for changing only the direction of the jet flow without moving the intersection point of the jet flow and the irradiated light.

(2) Registration of a utility model characterized in that the bubble removal means is formed by providing an introduction section thinner than the sheath flow forming chamber on the upper side of the sheath fluid inflow tube, and opening the tip of the bubble removal tube there. A microparticle analysis and fractionation device according to claim (1).

(3) the jet flow direction changing means comprises a holder that holds the jet nozzle, an arcuate rail fixed to the base, and a guide portion of the holder that engages with the rail and slides along it; The microparticle analysis and separation apparatus according to claim 1 of the registered utility model, characterized in that the center of curvature of the arcuate rail is configured to coincide with the tip of the nozzle.
