摘要

PROBLEM TO BE SOLVED: To provide a particle counter that improves detection accuracy of particles contained in discharged droplets and has high productivity capable of detecting the number of particles in the droplets even when the number of droplets discharged per unit time is increased.SOLUTION: A particle counter 1 includes: light irradiation means 30 for irradiating with light L a plurality of droplets 210 that contain particles 200 capable of emitting light when irradiated with the light L and are discharged from different places; light receiving means 41 for receiving emitted light Lf from the particles 200 irradiated with the light; and particle number counting means 50 for counting the particles 200 contained in the plurality of droplets 210 based on the emitted light Lf received by the light receiving means 41.SELECTED DRAWING: Figure 1
