Abstract
Particle analyzers are described that include a cell for receiving a particles-containing liquid; a light source for irradiating light onto the particles-containing liquid; a photo-detector for detecting optical information from particles in the particles-containing liquid and converting the optical information into an electric signal; a temperature sensor for detecting a temperature of the particles-containing liquid; and a signal processing section for calculating an analysis result of the particles on the basis of an output of the photo-detector and an output of the temperature sensor. Particle analysis methods are also described.
