Abstract

[Problem] To provide a particle detecting device able to detect particles accurately. [Means for Resolution] A particle detecting device comprising: a frame 1; a chamber 2 that is disposed within the frame 1; a sample injection flow path 3 for injecting, into the chamber 2, a fluid that includes particles, connecting between a from a first inlet opening 11 that is provided in the frame 1 and an injection nozzle 21 that is disposed within the chamber 2; an adjusting mechanism 5 for adjusting the state of the fluid within the chamber 2 by supplying a fluid, from which the particles have been removed, into the chamber 2 through an adjusting flow path 4 that connects to the chamber 2 from a second inlet opening 12 that is separate from the first inlet opening 11 that is provided in the frame 1; and a detecting mechanism 23 for detecting particles included within the fluid, by shining a light into the fluid that is blown out from the injection nozzle 21.
