ABSTRACT OF THE DISCLOSURE The apparatus for analyzing particles classifies or counts components in sample liquid by image processing, by passing a liquid sample of urine or the like in a flattened flow. This apparatus for analyzing particles comprises sheath liquid supply means (21), sample liquid discharge means (18), temperature sensor (36) for detecting the ambient temeprature, temperature measuring circuit (38) for measuring the temperature depending on the changes of the temperature sensor, and driving circuit (34) for driving the sample liquid discharge means by correcting the sample liquid discharge flow rate depending on the signal from the temperature measuring circuit. Moreover, the sheath liquid is supplied at a specific pressure, and the sample liquid discharge quantity is corrected depending on the ambient temperature. When changed to the high scale factor taking state or low scale factor taking state, a different correction rate is set. Thus, if the environmental conditions such as temperature should vary, the sample liquid volume is kept constant, so that particles may be analyzed at high precision. - 29 -
