Abstract
Disclosed is an apparatus for analyzing fine particles such as blood cells in a fluid such as blood, the apparatus comprising a device for generating electrical signal pulses from the specimen particles which have passed a detecting section such as, for example, a flow pass. The signal pulses are compared with a predetermined threshold, and specific information concerning the specimen particles is detected for a period which is determined on the basis of the signals produced by delaying the signal pulses, from a moment at which the threshold value is exceeded by each signal pulse.
