摘要： A system for monitoring non-volatile residue concentrations in ultra pure water includes a nebulizer for generating an aerosol composed of multiple water droplets, a heating element changing the aerosol to a suspension of residue particles, and a condensation particle counter to supersaturate the dried aerosol to cause droplet growth through condensation of a liquid onto the particles. The nebulizer incorporates a flow dividing structure that divides exiting waste water into a series of droplets. The droplets are counted to directly indicate a waste water flow rate and indirectly indicate an input flow rate of water supplied to the nebulizer. The condensation particle counter employs water as the condensing medium, avoiding the need for undesirable chemical formulations and enabling use of the ultra pure water itself as the condensing medium.

摘要： A high performance liquid chromatography system employs a nebulizer with a flow restriction at the exit of its mixing chamber to produce finer droplets, and an adjustable impactor for increased control over droplet sizes. Downstream of the mixing chamber, the nebulizer can incorporate tubing that is permeable to the sample liquid, to promote aerosol drying through perevaporation. A condensation particle counter downstream of the nebulizer uses water as the working medium, and is adjustable to control threshold nucleation sizes and droplet growth rates. A particle size selector employing diffusion, electrostatic attraction or selection based on electrical mobility, is advantageously positioned between the nebulizer and the CPC.
