A liquid-suspended particle analyzer includes: a fine liquid droplet producing device for atomizing a liquid pumped from a sample container by a fixed-displacement pump to produce fine liquid droplets suspended in a carrier gas; an evaporator for evaporating the liquid parts of the fine liquid droplets to produce an aerosol of the carrier gas and particles suspended in the carrier gas; a differential mobility classifier for classifying the particles of the aerosol by particle size according to mobility; and a Faraday cup electrometer for counting the respective numbers of the particles of the particle groups classified by particle size by the differential mobility classifier so as to determine the respective particle concentrations of the groups. The fine liquid droplets producing device includes an electrospraying device adapted to convert the liquid supplied by the liquid supply device into charged fine liquid droplets; and an atomizer adapted to suspend the charged fine liquid droplets produced by the electrospraying device in the carrier gas.
