Abstract: An irradiation optical system 12 irradiates a fluid flowing in a flow passage 2a with one light among a plurality of lights obtained by branching light from a light source 1 and forms the detection area. A detection optical system 13 makes scattered light with a different direction from an optical axis of the irradiation optical system enter a beam splitter 17 among the scattered lights from particles contained in the fluid in this detection area. Meanwhile, a beam expander 16 makes another light among the plurality of lights enter the beam splitter 17 as reference light. A detector 4 receives an interference light, by the scattered light and the reference light, obtained by the beam splitter 17 by light receiving elements and generates a detection signal corresponding to the interference light. A counting unit 6 counts the particles based on this detection signal.

Abstract: A particle counter for chemical solution in this disclosure uses a flow cell through which a chemical solution including particles flows, a laser light, and a light-receiving element array. Scattered light from the particles passing through a detection region on an optical path of the laser light in the flow cell is condensed to the light-receiving element array. The laser light in the center of the detection region has an energy density of 3×108 mW/cm2 or more. Each of plural light-receiving elements (a) is larger in length and width than a spot diameter of the scattered light, and (b) receives the scattered light from a region with a size of 760 μm2 or less included in the detection region. The signal processing unit counts the particles passing through the detection region by use of a threshold corresponding to the smallest measurable particle size of 0.03 μm.

Abstract: A particle counting system includes a collector, a liquid input/output operation executing means, and a particle counter. The collector performs a collecting operation to introduce the surrounding air into a container storing a liquid to collect airborne particles in the liquid. The liquid input/output operation executing means executes a series of liquid input/output operations to supply an additional liquid for the collecting operation to the collector and discharge the liquid after the collecting operation from the collector. The particle counter measures the number of particles contained in the liquid discharged from the collector with the series of liquid input/output operations.

Abstract: A flow passage is irradiated with irradiation light, and light scattered from a particle contained in a sample passing through a detection region that is formed in a prescribed section is condensed at a position obtained by extending the prescribed section in a flow direction of the sample and captured at a prescribed frame rate. Then movement amount of the particle due to Brownian motion in directions perpendicular to the flow direction on the basis of captured plural frame images. Furthermore, a particle size of the particle is determined by correcting the movement amount using correction values that were obtained in advance corresponding to each of defocus positions for correcting errors of movement amount in the images caused by magnification.
