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.

Abstract: A liquid container comprising a base having openings that communicate from the front surface to the back surface, and first and second sealing plates that seal the openings from both sides of the base to form internal spaces, wherein the sealing plates comprise a first heat exchanging member for heating or cooling the internal space from the front surface of the base and a second heat exchanging member for heating or cooling the internal space from the back surface of the base.
