A particle beam forming device for forming either a linear or conical particle beam from a particle source in which particles are dispersed in a gas, includes: a reduced-pressure vessel in which pressure is reduced; a particle beam generating unit, which has one end arranged outside of the reduced-pressure vessel and an other end arranged inside the reduced-pressure vessel, and which captures the particle source from outside the reduced-pressure vessel and introduces the particle beam into the reduced-pressure vessel; and a particle beam evaluating unit for evaluating a spatial distribution of the particle beam inside the reduced-pressure vessel.

A method of analyzing microparticle compositions and a microparticle composition analyzing device are capable of quantitatively analyzing the mass concentration of air microparticles online for each chemical composition. The particle ray of microparticles in an air sample is converged, and is irradiated onto a narrow domain of a capture body which includes a mesh-shaped structure for capturing the microparticles in the particle ray while removing surplus gas phase components, and the microparticles are captured. Then, the narrow region is subjected to concentrated irradiation of energy rays, and the microparticles that are captured by the capture body are vaporized, sublimated or reacted to yield a desorbed component, which is analyzed.
