Abstract:
A particle measurement apparatus comprising:a particle signal detecting section for detecting a particle signal with respect to a plurality of particles, the particle signal representing characteristics of each particle; a false signal generating section for generating a false signal corresponding to the particle signal; a selecting section for selecting the particle signal or the false signal, a non-linear amplifier; a first calculating section for receiving the signal selected by the selecting section through the non-linear amplifier to calculate a characteristic parameter; a second calculating section for receiving the signal selected by the selection section not through the non-linear amplifier to calculate the characteristic parameter; a comparison section for comparing the characteristic parameters calculated by the first and second calculating sections respectively when the selecting section selects the false signal; a storage section for storing a comparison result of the comparison section; and a compensating section for compensating the characteristic parameter calculated by the first calculating section on the basis of the comparison result when the selection section selects the particle signal.
