Abstract
A sample liquid flow containing particle components such as blood and urine is illuminated with light, and signals from particles are detected, and the particles are thereby analyzed. In this apparatus, using a prism or a diffraction grating, spectra of light signals are obtained, and more specific information regarding the particles is obtained. The fluorescence from the particles is separated by a prism or diffraction grating and classified into wavelength, the intensity of the obtained fluorescence spectra is amplified by an image intensifier, and the intensity is measured for each wavelength by an image sensor.
