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.
