Patent ID: 6892142

Claim:
A liquid-suspended particle analyzer for analyzing particles suspended in a liquid, comprising: a liquid supply device that supplies a liquid to be analyzed; a fine liquid droplet producing device, including an electrosprayer and an atomizer, that produces fine liquid droplets suspended in a carrier gas supplied to the atomizer by atomizing the liquid supplied by the liquid supply device; a radiation source provided within the atomizer for charging the charged fine liquid droplets produced by the electrosprayer in a Boltzmann equilibrium charted distribution; an evaporator connected to an outlet of said atomizer that produces an aerosol of the carrier gas and particles suspended in the carrier gas by evaporating the liquid parts of the fine liquid droplets produced by the fine liquid droplet producing device; a classifier that classifies the particles of the aerosol produced by the evaporator into particle groups by particle size; and a particle analyzer that analyzes the particle groups of the particles classified by particle size by the classifier.
