FINE PARTICLE ANALYZER AND FINE PARTICLE ANALYZING METHOD

摘要

PPROBLEM TO BE SOLVED: To provide a fine particle analyzer capable of separating fluorescence emitted from fine particles or a fluorescent substance labeled with the fine particles into a plurality of wavelength regions and individually detecting the separated fluorescence without arranging a plurality of detectors. PSOLUTION: The fine particle analyzer is equipped with a light source 1 for irradiating the fine particles P with light, an acoustic optical modulator 8 for diffracting the fluorescence emitted from the fine particles P by irradiation with light, a slit 9 for permitting only the diffracted light of a diffraction center wavelength region in the diffracted light from the acoustic optical modulator 8 to pass, and a detector 7 for detecting the diffracted light of the diffraction center wavelength region having passed through the slit 9.
