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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Particle counter for chemical solution","description":"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.
