Abstract
A method and apparatus for measuring particle concentration and size distribution of particles in liquids. The method involve separating dissolved and particulate residues in liquids for determination of the size and concentration of the particulate species. The method includes the steps of forming an aerosol from the liquid sample to be analyzed, evaporating the droplets in the aerosol to dryness, and detecting the particles. An apparatus for separating dissolved and particulate residues in liquids for determination of the size and concentration of the particulate species is also disclosed. The apparatus includes a droplet former, a dryer communicatively connected to the droplet former, and a detector communicatively connected to the evaporator for detecting particles.
