Abstract
A light scattering type particle detector in which the S/N ratio is improved includes a particle detecting region D which is formed by irradiating laser light La on sample fluid and a light receiving array 5 which receives scattering light Ls due to particles which pass through the particle detecting region. The light receiving array 5 is formed to be circular by arranging a plurality of photoelectric converters Pd1-Pdn in a plane alignment. The particle detector also includes an adder 6 which adds the output from the plurality of the photoelectric converters Pd1-Pdn.
